Check out Steezy Grossman. He was a gross-out "comedian" before Blippi. He did a Harlem Shake video where he deficated on a completely nude guy in a bathroom.
He used the DMAC to have all videos removed from the web and YouTube, to cover his tracks.. You can still find it though.
Pretty nasty. Now he's doing children's videos. Ugh. All the current profiles promote that was in the USAF and completely skip the 8 or so year period that he was a gross-out comic. He was in the USAF a whole two years.
EDIT: Totally forgot, he set-up a big tour for parents to take their kids see a live Blippi show. He used an impersonator and pissed off a lot of parents. Ticketmaster had to refund parents who were upset.
