Mike Tyson recently made an appearance on the popular Brazilian television program "Caldeirao do Huck" and what he did was quite surprising. 

Challenged by host Luciano Huck, "Iron Mike" sang the classic song "The Girl from Ipanema,” in a duet with Daniel Jobim, the grandson of the classic song’s original composer. 

The performance took place mainly in English, with a hint of Portuguese, Brazil’s native language.

Check out the hilarious video of Tyson singing while wearing a bright white sport coat, panama-like hat and bow tie.
