Monica: I'll prove it. About a week ago I was wearing those jeans, and I dropped a pen in my lap and it left an ink stain on the crotch. Now, when she comes back, I will find it and show you that stain.

Monica: I guess.
Chandler: So, shouldn't we give her the benefit of the doubt before we go snooping around her crotch?
