The Pontifical Mission Societies launched a campaign called Joke with the Pope, which encourages people to donate their favorite joke to the pope. The winner of the contest, which will run until October 2, will be named honorary comedic advisor to the pope, and one charitable cause will receive a $10,000 donation. 

Contestants choose one of three causes to support: helping street children in Buenos Aires, Argentina; housing the homeless in Addis Ababa, Ethiopia; or feeding the hungry in Nairobi, Kenya. Here's the submission from Bill Murray, honorary advisor for pontifical comedy:
