Mike Tyson -- Dancing MACHINE!!!!

So ... Mike Tyson was on a celebrity dancing show in Argentina last night -- and HE KILLED IT!!!!!!

Tyson and his wife Lakiha Spicer danced their asses off on a show called, "Bailando 2011" ... Argentina's version of "Dancing with the Stars."

After the groovefest ... Tyson called his dance instructors up on stage to personally thank them for coming to his home in America to train them for the show.

Just last year, Tyson appeared on a dancing show in Italy. Think he'll ever do the show here in the U.S.?
