- Grandpa Max: We called ourselves The Plumbers. Officially we didn't exist. We were the guys who fixed the problems no one else could: extraterrestrial, extrasensory, extraordinary.
- Ben Tennyson: [as emergency vehicles pass them] All right! Could be a chance for The Plumbers to go back to work.
- Gwen Tennyson: [groans] You should start by unclogging that hairball from your brain, Mr. Plumber.
- Ben Tennyson: Ah, you're just jealous 'cause you're not part of the family business.
- Grandpa Max: There is no "family business." My hero days were over a long time ago.
- Ben Tennyson: Well, mine are just getting started.
- Ben Tennyson: [Ben and Max are under attack by a large alien] We need some muscle to stop this thing. Four arms of muscle!
- Grey Matter: [after activating the Omnitrix] Grey Matter? I said muscle, not miniscule!
- Grandpa Max: And then, kablamo, no more Vilgax. Or so I thought, until today.
- Ben Tennyson: Whoa, you were a hero?
- Grandpa Max: I was just a guy doing a job.
- Gwen Tennyson: And you knew about the watch the whole time?
- Grandpa Max: Not really. Just rumor and scuttlebutt. I was surprised as you guys when it turned up on Ben's wrist.
- Gwen Tennyson: You always told us we could tell you anything, Grandpa. Guess you didn't feel the same.
- Phil: You know, once a plumber always a plumber. Ever think about getting back in the game, Max? You know, relive the glory days.
- Grandpa Max: No, thanks. I'm retired. And so are The Plumbers.
- Phil: Yeah, thanks to you. Once you took Vilgax out of the picture, the work just seemed to dry up.
- Ben Tennyson: I don't get it. How come you didn't tell Phil about the Omnitrix?
- Grandpa Max: That's on a need-to-know basis only, Ben. The less people who know, the better.
- Gwen Tennyson: Guess that's your answer to everything, isn't it, Grandpa?
- Gwen Tennyson: [as Wildmutt tries to talk to a pair of Vulpamancers] What did you say?
- Grandpa Max: Vulpamancers never were big on small talk, even with their own kind.
- Gwen Tennyson: Something's going on that Grandpa's not telling us about. Come on!
- Ben Tennyson: And pass up free room service? No way! I'm stayin' here!
- Gwen Tennyson: [cleverly] Nah, you're right. It's probably just some secret Plumber's mission. Better if we just stay out of it.
- Grey Matter: [climbing onto the back of a flying creature] Triggering the correct sequence of synapses should allow me some rudimentary motor control. Uh, sure wish I knew what I was talking about.
- Grandpa Max: I'm sorry I had to keep my past a secret for so long. I should have known I could trust you guys.
- Gwen Tennyson: It's okay.
- Grandpa Max: And for what it's worth, Ben, you would have made a great Plumber. Both of you!
- Gwen Tennyson: Hey, we're your grandkids. What do you expect?
- Gwen Tennyson: What about Phil?
- Grandpa Max: I think there's some things about this job we're better off not knowing.
- Phil: And don't worry. I'll be sure to tell Ben how your last words to me were how you wanted him to follow in your footsteps as my partner.
- Phil: It doesn't have to be this way. We could all work together!
- Grey Matter: No way. This is one hero who's not for sale.
- Phil: [aims the Null Void projector at Grey Matter] Then you're all gonna be very busy!
- Grey Matter: Sorry, I'm on summer vacation.
- Gwen Tennyson: Ben!
- [throws him a rearview mirror]
- Phil: [Grey Matter uses the mirror to reflect the beam back at Phil sending him to the Null Void] NOOOO!
- Gwen Tennyson: See ya!
- Grey Matter: And I definitely wouldn't want to be ya!
