Robert Downey Jr does what he wants, obviously, and what he wanted to do this time was find the ultimate Marvel 'stache. Yep, the science bros are going up against their technologically backward friend and the once upon a time owner of the best pornstache.

Mark Ruffalo was already ready with a collage of his pictures.
