Also, I had to tell you that I played a little MC Hammer in my calculus class.
I have a disability which allows me to not-hear music. Usually this disability boosts my immunity to ear-worms. However, hearing the song four times in one day was too much even for me. It's in my head now, but good.
Anyway, I was teaching about asymptotes. I played the song, and then I blew their minds with a little bit of this action:
MC Hammer was wrong. You can touch an asymptote. Repeatedly. Cool!
