Have you ever recieved a IM from someone who you had no clue who they were, and you never figured out?

I just got an IM from someone with the screename: Orange Julius333

They kept saying stuff like "yo yo I like kraft mac and cheesy nice and easy" or something along those lines. When I said "hey who are you?" they responded "A fate worse than death". Me: "hmm...Bill O'Riley?" them: "In your case, a mirror."

I have a strong feeling its someone from this MB...but I can't think of who. They typed with a big orange font and a blue background...it was ugly.
