Also the "Who's the Dummy?" questions are a sucessor to the Guest Host questions from Volume 3 and The Ride.
Polished Port: Party, an iOS release that can be played on TV or directly on the iPad.
Porting Disaster: The PC version of 2011 somehow had less features than its console counterparts, despite most of those features being more than possible on a PC. Almost all of the games supported at least 3 players on PC; 2011 supports 4 players on consoles, but only 2 on PC due to the new question format with money-based-on-time-to-answer not working so well when everyone has to share a "controller." When a concerned player tweeted a request for further clarification as to why the PC version was limited to 2 players to YDJK's twitter account, this insult◊ was what he got in reply.
The DS version of 2011 doesn't include the "Wrong Answer of the Game" and the "Nocternal Admissions" Questions.
The Scrappy: Billy O' Brien in 2011. Even Cookie hates him and is happy if you pick the Wrong Answer of the Game in the last on-disc episode, which gives you Billy.
Buzz Lippman is the Scrappy of the whole series, getting only one game and a Butt-Monkey joke in The Ride.
That One Question: In 2011, Episode 57, question 9ine requires you to memorize a code word that Cookie mentions at the very beginning of the episode. Because Cookie's opening lines up to this point have been one-off gags with no relevance to the game, this will likely blindside players who dismissed said code word as another one of those (or, even worse, skipped the intro entirely), basically reducing the question to sheer luck.
What Do You Mean, It Wasn't Made on Drugs?: The entire theme of Headrush's interface is, basically, the purest psychedelia of the 80s, complete with mostly black background, acid colors, distorted voices (that don't belong to the host most of the time), fast-moving grafitti slideshows/titles on the standby screen and really scary toy images for representing the players' avatars. Even the logo of this game looks precisely what you'd call surf-esque!
