Matt Damon is a man of many talents: Hollywood actor, father of three, Oscar-winning screenwriter, and Matthew McConaughey impersonator.

Anyone can do a passable Jack Nicholson or Robert De Niro impersonation, but young Matthew is a more obscure choice. But Matt Damon impersonates the hunky heartthrob so well, I could easily confuse the two if I close my eyes.

Of course, you can’t play Matthew McConaughey straight. His love of taking his shirt off and showcasing his sculpted abs is legendary. In this appearance on The Late Show with David Letterman, Matt keeps his tongue planted firmly in cheek as he remarks on the other Matt’s physique.
