Quick, I need suggestions.

What's a cheery (or cheesy) song that a grownup!John might use as a ringtone for Karkat? (Non-Homestuck fen: what song would you use for a best friend who's a co-leader of your friends group, has no secrets from you, and is comically over-the-top when riled?) Or it doesn't have to be a song; a comedy routine/punchline, TV show theme song, or anything else would also do. It just has to be relatively loud and definitely mood-killing. :D

Also, can anyone suggest movies which have a love triangle as a minor/background element, rather than being the main plot? Preferably a movie that a group of guys would have some interest in seeing.

Thank you all!
