During the fight scene, "Pencil Rain" is played.
Flansburgh sings a children's song that is very similar to a Barney song
called "Nice Is Good". This song might be found on Dial-A-Song at
718-387-6962, depending on what song is on that day.
An instrumental version of "Reprehensible" is played towards the end of the episode.
As the boys clean and then mess the house up again, "Until My Head Falls Off" plays.
Only incidental music is featured in this episode, although a lot of music is used included the tune "Monster", which can be found on Radio They Might Be Giants.
At the beginning of the episode, the boys are playing a violent video
game. Their mother turns it off and wants them to watch something less
violent. She changes the channel, and out of the TV (you only hear it) is
"Why Does The Sun Shine?", the slow version from the EP of the same name.
"Reprehensible" without vocals makes another appearance during a montage of how the family is handling living in a trailer while Malcolm is loving his new babysitting gig.
"Don't Cry" is played at the end of the episode, albeit a slowed down version. Instead of "How Can I Sing Like A Girl?", this performance should be subtitled, "How Can I Sing Like Barry White?"
"Monster", an instrumental that can be found on Radio TMBG and Dialasong.com makes a return appearance when all hell breaks loose at the academic circus.
