Drive-thru metal is really a thing, or at least this L.A.-based band is trying to make it a thing. Mac Sabbath (yes, that's really their band name) is a foursome of rockers who dress up as McDonald's characters and perform covers of Black Sabbath songs. And they even change up the lyrics so they're burger-themed.

On stage, they dress as Ronald McDonald, Grimace, the Hamburglar, and Mayor McCheese (with tusks and sans the top hat).

According to Mac Sabbath's Facebook page, they're not a joke band to sell t-shirts. They describe their shows as "Ronald Osbourne and the whole gang in full regalia playing all their hits like 'Sweet Beef' and 'Chicken for the Slaves' in a multi-media show with video, theatrics, audience participation and sing alongs."

We might have to study their new McDonald's-themed lyrics to do some singalongs. In the meantime, check out their rendition of "Iron Man," with the new title, "Frying Pan."
