Is it this joke?
A Frenchman, an Englishwoman and an Irishman find a wizard on the top of a tall cliff. The wizard orders them to jump off the cliff, but he also promises that if they say anything while falling, they will get it at the bottom of the cliff. So first, the Englishwoman jumps off the cliff and shouts, "Pillows!" and so she lands on some pillows. Then the Frenchman jumps off the cliff, and he shouts, "Hay!" and so he lands on some hay. Finally the Irishman runs to jump off the cliff, but he trips on a rock just before the jump and says, "Aw, shite!"
