Once upon a time there were these two bums walking down the railroad tracks, and the first bum, Fred, thought he smelled a nasty old smell. He asked his companion, Jeff, ''Did you s**t your pants?''
"Hell no," Jeff said.
They walked a few more miles and the smell got worse.
"Did you s**t your pants, Jeff?"
"I swear to the God almighty I did not s**t my pants," Jeff said.
So they walk three more miles and the smell gets just horrible.
Fred runs over and pulls down Jeff's pants and says, "I thought you said you didn't s**t your pants?!"
"I didn't." Jeff said.
"They're your pants."
