Chilli
A guy walks into a restaurant very hungry and impatient. After looking the menu over he decides on a bowl of chili. After ordering his meal he notices the man at the next table was not eating his bowl of chili.
Being as hungry as he was he politely says to the man "Excuse me sir, I'm very hungry and impatient. I noticed you have not been eating your chili. If it's allright with you, could I have your chili and when mine arrives I will give it to you". The man looks over at him with no answer but just a blank look on his face. Feeling that this was a "yes" answer the guy proceeds to take the man's chili and begins to eat fast and furiously.
When he reaches the bottom of the bowl he notices a dead mouse lying at the bottom. He then barfs up all the chili back into the bowl. Catching his breath he looks over to the man at the next table and says "Did you see that". The man looks over and says "Yeah, that's about as far as I got".
