My friend Quentin pointed me towards the Rock And Roll Confidential site, which is sort of a compendium of the worst bands in existence. I highly recommend you spend some time perusing their Hall of Douchebags section consisting of promo photos of bad bands and their commentary on them.
Some of the jokes are actually a little inappropriate (even for me) so if you are easily offended this site is not for you. If you aren’t easily offended you will very quickly be laughing your ass off.
Of particular note is this entry. :)
