Bill Clinton and the Pope both died on the same day.
Due to a clerical error, the Pope went to Hell, while Clinton went to Heaven.
When the Pope arrived in Hell, everyone realized the mistake. Due to an issue with the union, they couldn't swap the two until the next day, and the Pope had to spend the night in Hell, while Clinton spent the night in Heaven.
The next day the paperwork got worked out. On his way up to Heaven, the Pope ran into Clinton. Clinton asked the Pope, "How was your night in Hell?"
"Very educational," responded the Pope. "I've learned a lot from the experience, but now I'm glad I'm going to Heaven. I've been waiting all my life to meet the Virgin Mary."
"Ooh, sorry," said Clinton, "you should have been here yesterday."
