Face it: A head of hair like Michael Bay's deserves a little screen time. And sometimes the King of Big-Budget Crap just can't help himself. He's done cameos as a NASA scientist in Armageddon (presumably to keep an eye on the scientific accuracy of the film) and as a driver in Bad Boys 2.

Considering how terrible Bay's movies usually are, his occasional presence in them admittedly does little to worsen the overall effect. In fact, we might even bet on Bay in an act-off with Megan Fox.
