I think the CSI theme song (Who Are You? by The Who) is stuck in my head.

It's probably due to my mugging too much for Maths and Science.

"HOOOOO(who) ARE YOU? HOO,HOO? HOO,HOO?"

Looks like the whole Ms-Hoo-trying-to-get-maths-proofs-stuck-in-our-brains thing isn't working for me, because all I hear is her name and the first line of the CSI theme song repeated over and over. It's driving me crazy.
