According to Osho, don’t ask for a single joke—you’ll get two: 1) Two Italian nuns admiring tomatoes and cucumbers are overheard by a deaf elder who thinks they're discussing a Father. 2) After a salami explodes into heaven, an angel quizzes Joseph and Mary; Mary quips, without its net it looks like the Holy Ghost.
He answers with two Italian jokes: a nun’s mix-up about garden talk and a heavenly salami mistaken for the Holy Ghost.
