This is definitely their song! Now let's see... Eileen's song would be "I'm So Hot For Her and She's So Cold" by the Rolling Stones, and Pops' song would be "Lazing on a Sunday Afternoon" by Queen. If only there was a song about MY MOM!!!
XD Mordecai and Rigby both have bad singing voices but if they cover this it would STILL, by far, be better than the Kidz Bop version.
