This is a cover of the song "What's The Ugliest Part Of Your Body?" by Frank Zappa using a sample of the song.

Here are the lyrics:

Uh, yeah
Mother fucker
It's your mind, mother fucker
I think it's your dick

No one ever stops to think
What has become of me?
When to buy this or that
Selfish disregard of anything but tat

Lemme teach you a little lesson in anarchy
And fucking rape you in the ass, you see?
I'll let you mother fucking scream until you
Lose mother fucking consciousness or your sanity

Whatever comes fucking first, you'll mother fucking die
As miserable as your fucking existence
Without much persistance
Ripping into that flesh you call your existence

What's the ugliest part of your body?
What's the ugliest part of your body?
Some say your nose
Some say your toes but I think it's your mind
I think it's your mind
