This uh, thing, looks a little like the dude who used to show up at sporting events and mug for the cameras a couple decades ago. (Although he seems to have put on about 70 pounds, grown a huge rack, and moved the rainbow coloration from his head hair to his beard).
And this guy (on the right) looks a little too much like Paul Stanley (of the band KISS).
Last I heard, Rainbowhead went nuts, got into a shootout with the cops, and was sentenced to life in prison. The Straight Dope website (
http://www.straightdope.com/ ) has more on him; do a a search for Rollin (sp?) Stewart.
