Fire & Ice, they're watching you. They see your every move.

The story:

I was in class, and I sang it under my breath. My classmate and friend turned to me and said "what did you just say?" and I told him I was singing the Hall & Oates song. He thought I was joking with the Fire & Ice, and when he realized I really thought those were the words, he started laughing so hard he couldn't breathe or control it and the teacher called us out.
