That Is Gross

Three men walk into a bar. The barman tells them, "If you can sit in my basement for a day, I'll give you free beer forever."

The first man walks out after five minutes and says, "It's impossible, you got a swarm of flies in there."

So the second man tries his luck, but can't take more than an hour.

Finally, the third man goes down. When he returns a day later, the others ask him how he did it.

He says, "Easy! I took a dump in one corner and sat in the other corner!"
