If you’ve been lurking YouTube for Eminem rarities or are the proud owner of everything he’s ever recorded, you will have already heard this Eminem track from 1988, but for everyone else it’s a cool bit of hip-hop history. “Pooh Butt Day” is a song Em recorded with Chaos Kid (who’s in the shopping cart in the picture above), believed to be from 1988, which would make Eminem 15 or 16 years old.

The song was shared by a poster on Reddit yesterday, and you can check it out below. Eminem comes in around the two minute mark.
