Where is my head?
Where are my balls?
Can you save me from myself?

The story:

After hearing this song a couple times after getting the CD I was like "Balls?" And the second time they sing that verse it sounds more like balls than bones, so I decided that was it and would sing it that way. The next day my sister said "Dude, that's not balls! It's bones." I felt pretty stupid singing balls. I still do 'cause it's funny.
