The cast of The Avengers recently sat down with MTV's Josh Horowitz to play a game of "Whose Bicep Is It Anyway?"
They started off strong with Captain America's guns.
Then things got a lil' cheeky with Black Widow's toned arms.
And everyone wanted to lay claim to these ironclad muscles...
...and nobody, not even Thor himself, could identify those hammer-wielding muscles.
But everyone immediately identified Bruce Banner's hairy arms and purple tee.
Avengers = Muscles on muscles on muscles.
