From the Weekly World News, December 7th, 1993:
Angry bride Andrea Braysted was so furious after her sister Carol smushed a cream pie in her face during her wedding reception that she got three friends to help her even the score - by holding Carol down and shaving her bald as a melon!The story describes the wedding, Carol's smushing of the pie into Andrea's face, and how they're no longer speaking to each other.
The Weekly World News is one of those sources that you have to take with a grain of salt, of course, but they do know a good story. They liked this one so much, in fact, that they ran it again in 1999, virtually unchanged. I guess the sisters must be twice as mad at each other now. :-)
