My friends and I would sing this song over and over and over again, at school, over xbox live, etc. I've seen all of these, my favourite is the halo reach noob song. "If you're a noob playing halo reach, don't be afraid, come and sing along with me. When I'm on xbox I'm proud to say, I have no friends, but I'll play online all day." A while ago I actually memorized the entire song, it became an inside joke between my friends, I think I started it.

Ahh yeah, I used to do the same (over Xbox, at least) with my cousin.
