Sullivan's Ass (or Butt) is a popular gag in Nova and Sp00n's community. It was slowly becoming an internet meme, until the Dead Rising 2 (see history) lets play ended. It is rumored that Nova and Sp00n will return for Dead rising 2: off the record.
When the two we're doing their Dead Rising 2 playthrough, the two joked around about Sullivan's, a main character in the game, ass similar to Nova's Talking Butt. During the playthrough, 'mutant zombies' we're made by a gas, the two joked that it was Sullivan's poop stink.
- On Nova's channel, his ad is a picture of Sullivan and a text saying Sullivan's Ass likes T-Shirts.
