* CrazyAwesome: Very frequently.
* CreatorBacklash: [[InUniverse During his stand-up]], Bill says that he quit ''Series/NeverMindTheBuzzcocks'' to preserve his dignity, as he didn't want to keep having to do things like hum "Toxic" by Creator/BritneySpears to "some gormless indie halfwit".
* CrowningMusicOfAwesome: ''"Human slaves... in an insect nation! AAAAH-'''AHHHHHH!'''''"
** If he's got any manner of instrument in hand, this probably will ensue.
** A special mention for the note perfect chorus of Gary Numan's "Cars" played on a giant rack of rubber squeeze horns. And singing the whole thing in French.
* HilariousInHindsight: [[http://www.youtube.com/watch?v=KpT0fzz1m4M Lunge Wildly at the Pope]]
** Bill's frustration at the BBC for not playing the entirety of the snooker theme in Cosmic Jam "PLAY THE REST OF THE TRACK! They never play it!" is even more understandable these days with the entire tune being freely available on [[http://www.youtube.com/watch?v=7GkgoeKHsXI the web]] - it's a complete instrumental track and it's really very good. Although it never turns into ''Smells Like Teen Spirit''.
** And speaking of the Pope: Bill did his "Pope's Doorbell" skit back when the Catholic Church's resident Emperor Palpatine lookalike champion Benedict XVI was pope, playing off the utter absurdity of the situation. But now that we have Pope Francis, a mellow and by all appearances fun-loving pope, it's actually even funnier because there's something about him that suggests he'd totally be on board.
* MemeticMutation: "ROFLYSST," which stands for "rolling on the floor laughing [[FridgeLogic yet somehow still typing]]," a chatspeak expression he thinks the internet needs.
* NightmareFuel: According to him, ''TheMagicRoundabout'''s theme music contains a section of this.
** He also comments on the scariness of the ''Series/{{Mastermind}}'' theme. TruthInTelevision, as the creator of the show based the concept on his experiences of being interrogated by [[ThoseWackyNazis the Gestapo]].
* OneOfUs: He is a massive ''Franchise/StarTrek'' fan, even going so far as to name his son [[Series/StarTrekDeepSpaceNine Dax]]. Which was actually named after a childhood friend but you try telling the internet that.
** He is also known to wear anime paraphernalia, appearing in ''Anime/DragonBall'' and ''Manga/{{Naruto}}'' t-shirts in separate episodes of ''Series/{{QI}}''.
** He also seems to be a big fan of ''Literature/TheLordOfTheRings'', and apparently just missed out on landing a part (according to ''Part Troll''). [[HilariousInHindsight Which becomes way funnier]] considering his [[https://www.google.com/search?q=bill+bailey+theoden&source=lnms&tbm=isch&sa=X&ved=0CAcQ_AUoAWoVChMI3f_d4YyLyAIVxQmSCh2vRARL&biw=1708&bih=793&dpr=0.8 disturbing resemblance to Bernard Hill as King Theoden]].
* ThisIsYourPremiseOnDrugs:
-->"TV writers, they often use "acid" as a kind of a shorthand for "wacky" ? they'll say something like "This sitcom, it'll be like Terry And June ON ACID! Imagine what that'll be like!" Yeah, I can imagine what that'll be like ? that'll be Terry examining the floral pattern on a plate for four days..."
** He also once made the observation that the original theme music to ''Series/TheBill'' was great because it was "subversive"... in that it was a reefer tune disguised as the theme music to a cop show.
** And his own TheyChangedItNowItSucks moment on ''Series/{{Room101}}'' for the 'new' reworked Bill theme for being a generic 'pop' tune in 4/4 time when the original was in 7/4 time.
