How do you pump up the testosterone on a song by Metalocalypse's Dethklok? Make Batman the lead singer and send him rocking with his iron buns and his backup band—made up of Red Hood, Nightwing, and Robin on the drums.
This video might not be terribly safe for work depending on how your work feels about Bat-groin and Bat-butt. The folks at ArhyBES came up with this animated goofiness, taking Dethklok's "Face Fisted" and redubbing it "BATFACE"—covered by the Children of Batman.
