Smeghead.

A discussion I had about smegma this weekend (as you do) reminded me of the great knob cheese debate which took place a few months ago on my old MySpace Blog. It's an entertaining read.

Then of course, Wikipedia goes a step further. If you're not eating, go to http://en.wikipedia.org/wiki/Smegma and click on 'Images of Smegma' near the bottom of the page.
