Two Yankee pitchers traded LIVES!
If this sounds strange, it's because it is. In 1973, Yankee pitchers Fritz
Peterson and Mike Kekich called a press conference where they announced that
they had traded families. The men were going to swap wives, children and even
pets.

The trade ended up working better for Peterson, because he's still married
to his swapped wife, and had 4 kids. Kekich divorced soon after.
