The Butthole Surfers’ “unique” take on Black Sabbath’s “Sweet Leaf”. One of the greatest openings to a song ever:

“Daddy, what does regret mean?
Well son, the funny thing about regret is,
It’s better to regret something you have done,
Than to regret something you haven’t done.
And by the way, if you see your mom this weekend,
Be sure and tell her, SATAN, SATAN, SATAN!!!”

From the 1988 album “Locust Abortion Technician.”
