Quote from Dick in A Nightmare on Dick Street: Part 1
Dick: At first, all Sally ever did was complain about how I forced her to become a woman, but now all the time it's "Look at my body. I am so hot." Dr. Goldberg: This is your daughter? Dick: Sally? Uh, no, she's my sister. Dr. Goldberg: I'm sorry. It's just that she's 20 years younger than you. Dick: Oh, do you think I should make her be my daughter? Because that's doable.
