5. Judas Returns
Johnny Damon was a postseason hero for the Boston Red Sox up until he traded his red socks for navy pinstripes for $52-million in the winter of 2006.
On May 1st of that same year, Damon returned to Fenway greeted by vulgarity and boos from the place he called home for four years.
In addition to the boos, Damon was showered with dollar bills as Red Sox fans considered him to be a sell-out. This is a classic example of how fans react when someone leaves their beloved team for a hated rival.
