Just when you thought you had seen it all, former heavyweight champ and ear biter Mike Tyson appeared on a show in Brazil to sing "Girl From Ipanema".  It's not the 1st time we have heard Iron Mike sing.  You might remember in "The Hangover",  his rendition of Phil Collins’ “In the Air Tonight” before punching Zach Galifianakis’ lights out.

Here is Mike Tyson on the Brazilian television show Caldeirão do Huck, singing the  “Girl from Ipanema”. Thanks to YouTube.
