23 Skidoo!
Sorry, that was an old Bill Clinton slogan. I'll try to keep up now.
Ralph:
[after an argument with Alice on being young] She’s right, Norton. She’s right. There’s nothing wrong with somebody wanting to stay young. It’s my fault. Well, I’m telling you right now, Norton, I’m changing.
Ed Norton:
What are you gonna do?
Ralph:
I’m gonna start taking her to dances and roller-skating. I’m gonna learn all the new dances: the Big Apple, Suzie Q, the Continental, Hesitation Waltz, all of that. And I’m gonna learn all the expressions, too, like “Bo-do-dee-oh-do”, “23 skidoo”, and “I’ll kiss you later, I’m eating a potato”, all that stuff, I’m gonna learn. [Norton laughs] What’s so funny?
Ed Norton:
Bo-dee-do-do, 23 skidoo, I’ll kiss you later, I’m eating a potato! [laughs again]
Ralph:
What’s wrong with those expressions?
Ed Norton:
Boy, oh, boy, how can anyone so round be so square?
