Songs you know by... other reasons

Thanks (?) to a picture that I saw on montuos's G+ feed... here are some UNofficial names of fairly well-known songs. How many of them do you recognize, and do you have any others to contribute to the list?

The Viking Kittens Song (the one that prompted this post)

The MTV Song (This may be easy)

The Popcorn Song (I've also heard it called The Jiffy-Pop Song)

The Ajax Song

(Possibly more to come!)
