(Borrowed shamelessly from a friend:) Following the marginally successful Teacher In Space program, NASA decided to send up some religious leaders. So up go a priest and a rabbi on the Atlantis. After a few days in orbit they're back and in a news conference they're asked how it was. "It was simply magnificent!" exclaimed the priest "God's creation in its full glory." "And you, rabbi" asked one of the reporters. "Oy, I tell you it vas just awful." "Well, why?" "You vouldn't believe it, every five minutes it's de same ting: on vith the tfillin, off with the tfillin, on with the tfillin, off with the tfillin..." (For those of you with puzzled looks: Tfillin are sacred prayer scrolls in special leather holders. Each morning Every Jewish man is supposed to put them on his forehead and arm as part of morning prayer.)
