Yes, dammit, I'm sure

[SalBac]

Today's QOD: What question do you hate being asked? 

"Are you sure?" Yes. I'm sure. I wouldn't have said it or offered or handed you one or swallowed it if I wasn't sure.  Whatever it is, I'm sure.

Besides, what am I going to do? Say, "Gee, now that you made me think about it, I am being way too generous here. Let's forget the whole thing."

Surely then you'll ask, "Are you sure?"  AGGGHHHH!  Endless loop!!!
