The singing cyclist

It's a beautiful day for bicycle commuting, you've crested the hill, and it's downhill all the way to work. Traffic is light, the sun is shining, and the birds are singing.

So what are some really unfortunate songs to get stuck in your head if you're prone to singing out loud while you coast down the hill?

1) Gold digger, Kanye West
2) Anything from South Park

I got a couple of very strange looks yesterday.
