Shocking, but true! Bill Murray was once married to Sarah Jessica Parker -- on the TV show "Square Pegs."

Their totally inappropriate union took place during a very special episode of the high school dramedy, wherein Murray played SJP's substitute teacher. All the kids are forced to pair up in order to learn about the trials of marriage -- and Parker is stuck with the 15-years-older sub. Awkward!

Enjoy the full episode below.
