A man walks into a brothel...

So a man walks into a brothel. He's a little down on his luck and only has $5. He asks the woman at the front desk, "So what can I get with this?" and hands her the $5. She takes the money and says, "Second door on the left." The man goes to the room and sees a chicken on the bed. He's confused and searches the room for a woman. He fails to do so and looks at the chicken. "Well, I guess it's better than nothing." He proceeds to have sex with the chicken. Turns out it was the best he's ever had.

A week later he comes back with $1. "So, uhh, what can I get for this?" The woman at the front desk says, "First room on the left." He walks into the room and sees a bunch of guys crowded around a hole in the wall. He gets a chance to peek through and sees two sexy lesbians getting it on. "Man, they're really going at it," he says, "This is pretty crazy." One guy from the crowd says, "Oh that's nothing. You should have been here last week, there was a dude fucking a chicken."
