McConaughey Will Beat a Man's Ass

Matt McConaughey was caught yesterday sparring with a buddy outside of his Airstream love shack.

The hunky and unusually shirted (darn!) actor must be one tough fighter! Actually, this was part of Matt's macho goodbye ritual with a motorcycling pal.

Luckily for the pal, Matt is reach-challenged.
