I've heard lots of variations of the misheard lyric meme.
"There's a bathroom on the right"? Heard it.
"Let's pee in the corner"? Heard it.
"The dude I'm in"? Heard it.
But there is one that I heard recently that I hadn't heard before. Instead of "Smoke on the Water," someone quoted a lyric as "Slow Uncle Walter."
I like that.
