DONATIONS, PLEASE

Bob found himself amid a crush of excited people in the lobby of his office building.  He started to fight his way to the front of the crowd when he ran into a co-worker.

"What's going on?" Bob asked.

"Some religious nut's in the elevator," said his colleague. "The fanatic's soaked himself in gasoline, and he's threatening to set himself on fire. I'm taking up a collection for him. Want to donate?"

"Sure," said Bob. "How much have you collected so far?"

His friend replied, "Eight books of matches and six lighters."
