"Take a Dump On the Toilet" or "In The Bathroom" is a song by NintendoCapriSun. He wrote the lyrics to the tune of video game background music that plays while the player navigates Clock Town, the primary village in The Legend of Zelda: Majora's Mask for the Nintendo 64. The music for this game was composed by Koji Kondo and Toru Minegishi.
In part 33 of Let's Play The Legend Of Zelda: Majora's Mask, during a segment which was originally going to be edited out of the video had it not been for what happened, NintendoCapriSun seemingly comes up with his lyrics on the spot for great comic effect. At about 56 seconds into the video he sings,
"...get the toilet scrub brush,
You don't want your bathroom smelling,
Over to your house,
Oh, I fell through the floor it stunk so bad; I fell through the floor.
Take a dump on the toilet,
I am almost back now,
This song should not be confused with the other "Take a Dump On the Toilet" song that NintendoCapriSun wrote for Mega Man 2.
