I heard this morning and laughed.
It always makes me laugh because it reminds me of my dad. My dad, who always answers "Black Sabbath" when the question is "Who sings this song?" My dad, who makes every car trip memorable.
One time, we were coming back from my grandparents' in Missouri. We were nearing the end of the trip when this song came on the radio. The opening lyrics are "I've got a bad disease. But* from my brain is where I bleed."
My dad shifted in his seat and made up his own words.
"I've got a bad disease. IT'S CALLED TIIIIRED BUUUUTT!"
*Some swear it's "Up from my brain is where I bleed." Who cares. It's not really crucial to the story that I get it right.
