Not as classic as "Who's on first", but hilarious still.
My late cousin-in-law had one about three men staying at a hotel, and the bellboy jacking up the price, then feeling bad and giving part of it back. Worked one way, the problem makes sense, but when you work it backwards...
Did you go to school, stupid?
Yeah, and I came out the same way.
That's hilarious.
Sounds about right to me.
:D That's a new one on me, but I have to admire the logic though; more doughnuts for all!

I'm a huge fan of old black and white comedy times, and I love this skit.
