This one's not safe for the kids: Mac Sabbath is a Black Sabbath cover band that dresses like McDonald's Happy Meal characters. The band members revised the lyrics of popular Sabbath songs so that they relate more to food and less to death. The song Paranoid was rewritten as Pair-a-buns; The band's famous Iron Man was cleverly renamed Frying Pan.
A few choice lyrics:
Heavy longing for bed/
Fry these cows until you're fed
Throw out your raisin bran/
Frying pan lives again
