1. Johnny Depp: In 1990, he got "Winona Forever" tattooed on his arm, but forever turned out to be closer to four years. When he and Winona Ryder split up, he had it altered to read, "Wino Forever." He's since said that sentiment is "a bit more accurate" anyway.
2. Charlie Sheen: Nothing like meeting your soon-to-be-third wife to get you to remove your second wife's tattoo from your wrist: The "Denise" had to go (as did Denise Richards' "Charlie" tattoo) when Sheen met Brooke Mueller.
