Sports figure(s) involved: Fritz Peterson and Mike Kekichs
Year: 1972

In maybe the weirdest story in all of sports, Yankee pitchers Mike Kekich and Fritz Peterson swapped families in 1973, and not like Ric Flair and Rowdy Roddy Piper on ABC's Wife Swap. Like, for real. Kekich and Peterson made an offseason move to trade wives, children and homes. The deal worked out for Peterson who, to this day, is still married to Kekich's ex. Kekich, on the other hand, lost his touch on the mound and stayed with Peterson's former wife for less than a year. Let this be a lesson to you young arms out there who think it's a good idea to offer up your girl to some dude you met in the bullpen.
