* [[https://www.youtube.com/watch?v=RJSa_dLV1u8 Serenity Con 2007]]: Nathan straightens out Alan Tudyk about just what was said about the possibility of a sequel to ''Film/{{Serenity}}''. What makes it even better is that they start having a joke argument over the phone... and then you can hear Nathan start talking ''in the room where Alan is giving the convention talk'', miliseconds before the phone relays it.
-->'''Nathan''': Listen; Alan is a wealth of information, most of it false. If you want to know the real deal about Alan Tudyk, there's only one person you can ask, and that's ''me''.
* [[https://www.youtube.com/watch?v=OTL69m9CNM0 San Diego Comic Con 2010]]: At a ''Series/{{Castle|2009}}'' panel, Nathan and Stana Katic do a DramaticReading of "Richard Castle's" book ''Nikki Heat''. And it's the '''sex scene''' between Nikki Heat (modeled after Stana/Beckett) and Jameson Rook (modeled after Nathan/Castle). HilarityEnsues.
** Special mention goes to his mispronouncing "cologne" as ''"colog-na"'' and his antics during Stana Katic's turn to read. Nathan at one point decides to, um, cool off by dropping the ice cubes in his water inside his shirt, and after they've been Lord-knows-where, he stuffs them down the back of ''Creator/JonHuertas' (Esposito) shirt''.
* One of Nathan's best stories (and he has ''many'' great ones) is how he managed to get out of a speeding ticket. He was on his way to a set one day when he got pulled over for speeding and the cop came up to the car and Nathan pleaded with the guy to give him a break. The cop actually does because he recognizes that Nathan is an actor and says he'll give him a pardon if he gets an autograph. Ecstatic, Nathan whips out a pen and paper and starts writing to the cop while said cop dials up his wife and exclaims, "Baby, you'll never guess who I just pulled over! Creator/JasonBateman!" And not missing a beat, Nathan signed his name as "Jason Bateman" and went on his merry way. Subsequently, a scene in ''Castle'' has his character briefly mistaken for Jason Bateman.
* If you still don't believe Nathan is FunPersonified, take a gander at the Serenity [[http://youtu.be/GzZ9K26gHXg Behind the Scenes Feature.]]
* Three words: [[http://29.media.tumblr.com/tumblr_lz53l6yowq1qjzinuo1_250.png Google. Maps. Pose.]] Explained in context [[http://youtu.be/xccJlatRvvs here.]] We must find this!
* On his hit show ''Series/{{Castle|2009}}'', the titular Castle doesn't know who his dad is. At Comic Con 2010, someone asked who Nathan would like to play Castle's dad. [[http://youtu.be/gS33sS98kJ4 This is the result.]]
* [[http://youtu.be/tzNMtGx_cZc The Daly Show: Episode 7 "The Daly Superheroes" with NATHAN FILLION]].
* Once on [[Creator/EllenDeGeneres Ellen Degeneres]]'s show, reminiscing about his soap opera days, he explained the only faces you need for dramatic close ups. Number one: "Did I leave the stove on?" [looks confused]. Number two: "I did leave the stove on!" [looks troubled]. Look three: "No, I turned the stove off!" [looks confident and happy]. [[https://www.youtube.com/watch?v=TktV93g9H3g See it here.]]
** A variation from another interview has a cat instead of a stove. "Did I let the cat in?" [looks confused and caring] "I did '''not''' let the cat in!" [looks troubled] "Nah, I don't have a cat!" [looks beyond self-assured and positively happy].
* When asked whether he liked going to conventions and comic cons, he proudly and excitedly said there was even his action figure! When teased whether it looked like him at all, and he said that the profile was remarkable, but other than that it kind of looked like David Duchovny Surprised.
* He once [[https://twitter.com/NathanFillion/status/494944557042122753 photobombed]] Creator/KellyHu, then [[BlatantLies denied that]] [[ImplausibleDeniability it was him]].
* [[https://twitter.com/NathanFillion/status/493862631451537408/photo/1 A fan made a picture of him as God]], going berserk over Series/{{Firefly}} being cancelled. His response was merely to say "this doesn't go to my head at all".
** Which becomes HilariousInHindsight when Nathan went on to ''play'' God in ''VideoGame/SaintsRowGatOutOfHell.''
* [[http://youtu.be/Zfs8_daay-o His Jimmy Kimmel interview]] in which he admits that he likes to scare his housekeeper by doing things like hiding behind doors, between mattresses, and even hiding a little device that makes creepy noises behind the seat of her car.
* Anytime he calls one of his fellow Series/{{Firefly}} costars' during a panel.
