Another (kinda) related joke:
A guy is getting married, and his three friends, a carpenter, a electrician, and a dentist all decide to prank him on his wedding night. The carpenter and electrician are discussing thier plans, and ask the dentist what he is planning... he just chuckles and says "you'll see"
A week after the wedding, the newly married man gets home from his honeymoon, and writes a letter to his friends:
Regarding my wedding night:
The half-way cut through bed slats were a minor nuisance, and the AC current hooked into the door knob did not turn out to be an insumountable problem... but I'm gonna kill the SOB who put novacaine in the KY jelly!
