Chandler: What size shoes do you wear?
Joey: Uh, eleven. Eleven and a half.
Chandler: Great. My shoes are giving me a little problem on the dance floor. Can I borrow the boots from your costume?

Chandler: Those aren't eleven and a half.
Joey: Okay, fine, I'm a 7! All right, I have surprisingly small feet. But the rest of me is good. I'll show you!
