"The Cookie" joke

"Tell me something," asked Joe "how many cookies can you eat on an empty stomach, Pete?"

Pete thought for a while and answered, "Five, I think!"

"Wrong," said Joe, "because your stomach is no longer empty after you've eaten your first one. So the other four don't count! Gotcha, ha, ha!"

Pete, the dud, was impressed. I must try it on my wife, he thought to himself.

"Honey, how many cookies can you eat on an empty stomach?"

"Two", came the answer.

"Aw shucks, hon. If you had said five, I would have told you a nice one!"
