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!”
