Are you eating right now?  Then don't read this joke now.

A man enters a cafe and sits down.  He notices that the special of the day is cold chili.  When the waitress comes to take his order, he says, "I'll take the cold chili."

"I'm sorry, the gentleman next to you got the last bowl," says the waitress.

"Oh, I'll just have coffee, then."

After a while the man notices that the guy next to him who got the last bowl of cold chili is finishing a rather large meal and the chili bowl is still full.

He asks, "Are you going to eat that?"

The other man replies, "No."

"Would you sell it to me?"

"You can have it for free if you want it."

So the man takes the bowl of chili and begins to eat it.  When he gets about half way through the bowl, he notices a dead mouse in the bowl and pukes the chili back into the bowl.

The other man says sympathetically, "That's about as far as I got, too."
