But nothing compares
To all this blue and yellow bird poop, yeah

The story:

So my brother thinks eminem is amazing. He's told me a lot of the lyrics that he thinks are funny. I just figured this song was one of those funny ones. I swore I heard something funny when he was driving me to school and he cranked up this song so I asked him what the song was called. Even when he told me the song was called purple pills I didn't really get it. So I said "Did he say what I thought he said?"
"What?"
I listened again. "Oh he DID say it!"
"Said what?"
"Something about bird poop."
I think my brother almost crashed the car when I said that. He whipped his head around and was like "Blue and yellow PURPLE PILLS!" I think he was really happy to dump me out of the car at school.
