PRANKSTERS The wedding date was set and the groom's three pals -- a carpenter, an electrician and a dentist -- were deciding what pranks to play on the couple on their wedding night. The carpenter figured that sawing the slats of their bed would give them a chuckle or two. The electrician decided to wire the bed -- with alternating current, of course. The dentist wouldn't commit himself, but wore a sly grin and promised it would be memorable. The nuptials went as planned. A few days later, each of the groomsmen received the following note: "Dear Friends, we didn't mind the bed slats being sawed. The electric shock was only a minor setback. But I swear to God almighty, I'm going to kill whoever put novacaine in the K-Y Jelly!"
