- Cerebus: [Cerberus calls back on Doctor Fowler's private line] Don't hang up on me again... Don't do that.
- Dr. Eric Fowler: This is my private line.
- Cerebus: Yes, and I'm in that chair with you treating your patients... I know their secrets, their dirty little perversions... You don't beleive me?... Where shall we start? Creepy Mary, Bobby Boy, Kooky Eva?
- Dr. Eric Fowler: Who is this?
- Cerebus: You need a name?... I'm Cerberus, the hound of hell and all of my 50 heads
- Dr. Eric Fowler: Is this some kind of sick joke?
- Cerebus: Yes, but it is my turn to laugh. You... You turned me down as a poor treatment risk!... Me, a 170 IQ, and I am a poor treatment risk?
- Dr. Eric Fowler: Did I see you at one of my clinics?
- Cerebus: What difference does that make?
- Dr. Eric Fowler: Look, Cerberus, You're hostile... And maybe you have every right, but there just aren't enough psychiatrists to go around.
- Cerebus: So crawl in a corner and die!... Hang a "Do Not Disturb" sign around a corpse?... No Way! This mistake is not getting buried!... You're paying now, Doc. I want 5 grand, or I'll finish you and your sickies!
- Dr. Eric Fowler: Listen, Cerberus... You listen to me, and you listen hard!... I will not be threatened or blackmailed... You won't get a cent out of me... And don't phone again.
- [Doctor Fowler hangs up]
- Cerebus: [on the telephone, continuing to torment Eric Fowler] How does it feel to be licking the boots of a full-blown psycho?
- [makes suggestive licking sounds]
- Dr. Eric Fowler: [Doctor Fowler gets a phone call from Cerberus] Hello?
- Cerebus: Doc?
- Dr. Eric Fowler: Speaking.
- Cerebus: Hi, Doc... I'm wired into you, I know all about you.
- Dr. Eric Fowler: Wired in?... Aah, Big Brother watcheth, huh?... Well, thanks for the warning, old buddy.
- Cerebus: I'm not your buddy, and I'm not putting you on... I've been listening in to you and your patients for months.
- Dr. Eric Fowler: I'm sorry... I'm very busy
- [Doctor Fowler hangs up]
- Che Fong: [Checking on Doctor Fowler's phone line] Cerberus could be expert enough to equalize this phone tap.
- Cerebus: [Cerberus knows that McGarrett's team has found his bugs in the doctors office] McGarrett, keep your hands off those bugs!... Yeah, doc, this is your full-blown paranoid visionary coming to you from somewhere in paradise... You brought the cops, you get them out... NOW!
- Det. Steve McGarrett: [to Doctor Fowler after finding all the bugs, and hearing Cerberus' threats] Your office, your decision.
- Dr. Eric Fowler: Well, what do you suggest?
- Det. Steve McGarrett: Ignore him, call his bluff.
- Cerebus: [after hearing McGarrett order all the bugs removed from Doctor Fowler's office] Okay, doc..You'll be sorry for the rest of your life!
- Det. Steve McGarrett: Che, install a button on the doctor's phone so that he can signal us to tune in when that paranoid calls.
- Det. Steve McGarrett: [McGarrett and Dr. Fowler are talking about Bobby after he heard a tape from Cerberus] Doc, do you have any more patients as vulernable as this?
- Dr. Eric Fowler: [after McGarrett finds a bug in Dr. Fowler's jacket, and writes a note to the Doctor to kick Five-0 off the case] I've made up my mind, McGarrett... I've got my patients to protect. I can't let this happen again... I'll settle with him. Just get off the case!
- Det. Steve McGarrett: Doc, please.
- Dr. Eric Fowler: Stay away, understand?
- Cerebus: [Cerebus has Doctor Fowler's house bugged] Doc? Yeah, Doc, it's me... Sorry about the boy, but you wouldn't listen.
- Dr. Eric Fowler: In my own home?
- Cerebus: That's right, We've all got to live with our demons.
- Cerebus: [Imitating Creepy Mary] Oh, I'm going blind. I'm jaundicing... Doctor, I'm dying... That screeching crow!, I wouldn't treat her for her weight in gold!
- Dr. Eric Fowler: [Talking with Cerberus] If I found a way to get you immunity from prosecution, would you be willing to come forward and accept psychiatric help without any cost to you?
- Cerebus: [laughing hysterically] Beautiful, just beautiful!... The poor treatment risk shows a little muscle and BINGO!... A free pyschoanalysis, FREE!... Well, I don't need you, Doc!... I don't need anybody!... I am my own operation bootstrap!
- Cerebus: [Blackmailing Doctor Fowler] Alright, let's get to figures... It was 5 grand, now it's 10.
- Dr. Eric Fowler: I don't have that kind of money.
- Cerebus: SHUT!... Shut your mouth, or it will be 20!
- Danny Williams: [Calling all police units, trying to find Cerberus] This is Williams... Setup road blocks on the canal, corner of Ala Wai and McCully... Stop all cars with transmitter aerials. Look for tapes... Arrest all suspects.
- Det. Steve McGarrett: [McGarrett is getting a rundown of the suspects from Dan] Don't tell me he beat the computer... I'm beginning to beleive that 170 IQ bit... But an electronics wizard just doesn't spring from thin air... .He had to get his training from somewhere.
- Det. Steve McGarrett: [McGarrett and Doctor fowler are discussing catching Cerberus] Doctor, are you willing to take some risk?
- Dr. Eric Fowler: To put him away, yes.
- Carol Fowler: [Carol to Eric after reacting to Cerberus' bugging the house] You can't let this sadist pull your wings like some helpless fly!
- Cerebus: [after hearing Carol beg to be left alone] Doc, you tell your wife if she doesn't pipe down, I'll play tapes of you and Sharon making love
- [he makes panting sounds]
- Cerebus: ... And I'll make her listen to them in every corner of this house... In the kitchen, in the bedroom, in the hallway, MORNING, NOON AND NIGHT!... HAH RAH!
- Cerebus: [Cerberus is blackmailing Doctor Fowler] All right now, How about the 10 grand?... Have you got it?
- Dr. Eric Fowler: It's waiting at the bank.
- Cerebus: Good... Get it in that airline bag first thing tomorrow... And keep it with you wherever you go, and keep your car radio on... You got that?
- Dr. Eric Fowler: Yes
- Cerebus: [to Doctor Fowler after discovering that the payoff was tracked] You went to McGarrett again!... The first jolt wasn't enough for you!. You need more shock therapy... For starters you wasted that 10 grand. It's cop contaminated... You're gonna double it!
- Det. Steve McGarrett: [Meeting with Doctor Fowler] The faster we get you back to your office, the better... Cerberus trusts you about as far as he can throw this building.
- Cerebus: [to Doctor Fowler] Doc, Tell Carol to start selling her government bonds. I'm hard up for cash... And get back on that phone to your sickies. You're back in business full schedule tomorrow.
- Cerebus: [to Doctor Fowler after being caught] You looked right past me every day!... You spit at me at the Oahu Clinic, but I'll get you!... I don't care if it takes five years, ten years, twenty years, I'll get you Doc... I WILL GET YOU!
- [Cerberus spits at Doctor Fowder]
- Dr. Eric Fowler: [to McGarrett after Cerberus has been arrested] I don't know about you, but that right hook sure made me feel better.
- Det. Steve McGarrett: Too bad you can't cure a pyschotic with a right hook, huh Doc?
