Two blond-haired men named Bob and Ben go camping. They pack a
cooler with sandwiches and beer and set off. After two days of
hiking, they arrive at a great spot but soon realize that they’ve
forgotten to pack a bottle opener. Bob turns to Ben and says: “You
gotta go back and get the opener or else we have no beer."
"No way," says Ben, "By the time I get back, you'll have eaten
all the food."
"I promise I won't," says Bob. "Just hurry!"
Five full days pass, and there's still no sign of Ben.
Exasperated and starving, Bob gives in to hunger and digs into the
sandwiches. Suddenly, Ben pops out from behind a rock and yells: "I
knew it! I'm not f*cking going!"
