Uncle Jimmy: What do you mean unnatural?
Dr. Martin Ellingham: You have three times more testosterone in your system than is normal!
Uncle Jimmy: You didn't say normal. You said unnatural. Who are you to decide what's natural?
Dr. Martin Ellingham: I'm a doctor!
Uncle Jimmy: Oh, and that makes you the big man, does it?
Dr. Martin Ellingham: Oh, don't be so stupid!
Aunt Jennie: Jimmy!
Dr. Martin Ellingham: You've been taking testosterone supplements, haven't you? Where'd you get them from? A gymnasium?
Uncle Jimmy: Oh, so going to the gym's now unnatural, is it?
Dr. Martin Ellingham: You imagine that taking fistfuls of anabolic steroids is going to increase your chances of conceiving a child, yes?
Uncle Jimmy: Well, isn't it?
Dr. Martin Ellingham: No! It has the opposite effect. The brain gets the message to stop producing luteinizing hormone, which in turn arrests normal sperm production. Not only does it make you stupidly, moronically aggressive, it also renders you infertile!
Uncle Jimmy: Well, it's all right for you!
