Eric Cartman's musical in Butterballs

I had a chance to see the South Park's 'Butterballs' episode on the southpark website. The most enjoyable part of the episode, for me, was Eric Cartman singing about his vajayjay in the musical. Below are Eric's words -

Used to be chicks sang about their relaionships; now it's all "my vajayjay this, my vajayjay that." But clearly that's what sells. When was the last time you turned on a music video and didn't see some chick strumming a guitar singing about her vajayjay?

Oh you like my body
Yeah c'mon let's play
You can touch me anywhere
Except on my vajayjay
My heart says yes
But my vajayjay says no
