This dude on YouTube made a love song about Mario Kart. The surprising element here is some level of musical talent, and the song's considerable lack of suckiness.
The Third verse is my favorite: "The blue shell is coming / so I'll go ahead / If you hang behind / it'll hit me instead / but never look back / cause I'm down but not dead / I'll catch up to you." Heehee!

Don't try this at home.
