1) Many people remember the Shah of Iran, but few people remember his cousin, the Shan of Iran. This is because the unfortunate Shan had been subject to epilepsy since youth. It would have been a disasterous embarrasment to the family if the Shan's ailment had become public knowledge, so if anyone were present when he was struck by an attack of epilepsy, the palace guards had standing orders that those people must be killed immediately. Now, it came to pass that a grand party was thrown by the Shan to celebrate his wedding day, with many many guests in attendance. Yet crule fate was not to be denied, and in the middle of the party the Shan was sturck by another epileptic siezure. Some of the guests, having heard rumors of people mysteriously disappearing when with the Shan, realized what would come next and made immediately for the door, and a few actually escaped before the palace guards gained control of the crowd. The next day one of those who had escaped noticed someone else he'd seen at the party. He walked over and asked discreetly, "I say, where were you when the fit hit the Shan?" 2) In a shoe store: Come in and have a fit. measure, get the - of sb/take sb's -
