History BewareTheSillyOnes / LiveActionTV

* ''Series/{{Angel}}'' has the Groosalugg, a benevolent demon with [[UnevenHybrid human ancestry]] and an almost human appearance. Due to his demonic origins, he has physical powers that are on the same level as the titular hero. However, he is not exactly characterized by cleverness.
** In the fourth season, a demon appears, known only as 'The Beast'. And he's strong enough to easily defeat all heroes in a fight. At the same time, it also becomes clear that he cannot be smart enough to be the true BigBad.

* Shawn Spencer from ''Series/{{Psych}}'' is a perfect example of this. A complete jester who never takes anything seriously and seems harmless enough...until his loved ones are put in harm's way. Then he will hunt you down until you're "behind bars or dead". [[spoiler: quoted from an episode where Shawn takes down the man who shoots his father]].

** Piss him off by [[BerserkButton threatening his friend's life]] in front of him-and [[BewaretheQuietOnes you're screwed.]]

* Rick Castle of ''Series/{{Castle}}'' fame is a fun-loving geek of a bestselling mystery author, prone to coming up with ludicrously outlandish theories on the murder of the week. Threaten Beckett, or worse [[PapaWolf his daughter Alexis]], and ''you're done'': he's shot three criminals and [[spoiler:used the JackBauerInterrogationTechnique on one of his daughter's kidnappers]].

** The Doctor just wants to have a bit of fun. "There's no point in being grown up if you can't be childish sometimes," they say. They've been accurately described as a "madman with a box", and no one with their dress sense (no matter how much it changes) could ever be taken seriously. They've also stopped more villainous plots and saved more lives than could possibly be counted, and is outright ''[[TheDreaded feared]]'' by some of the most evil beings in existence.
** As befitting an EvilCounterpart, the Master sometimes shows shades of this. The Anthony Ainley and John Simm incarnations especially loved to bust out the EvilLaugh and add some flair to their villainy, while the Michelle Gomez incarnation seemed to enjoy pop music (well, one song in particular), but there is a very good reason the Doctor continually regards the Master as their worst enemy.
** Nardole, introduced in the 2015 Christmas special as TheDitz, and who later becomes the Doctor's "valet" of sorts, was solely comic relief until the end of [[Recap/DoctorWhoS36E5Oxygen "Oxygen"]], when he gives the Doctor a ''blistering'' TheReasonYouSuckSpeech for putting himself in life-threatening danger when he has a duty to be guarding the mysterious Vault underneath the University of Bristol. In addition to this, hints have been dropped that he has some kind of criminal past, and it's been revealed the ditzy behaviour from [[Recap/DoctorWho2015CSTheHusbandsOfRiverSong "The Husbands of River Song"]] was a case of ObfuscatingStupidity.

** On the side of the good guys: [[''Series/PowerRangersJungleFury'' Jungle Fury's]] RJ Finn. Very laid back to the point that it's always awesome to see him kick Rinshi and monster rear.

* Jack O'Neill of ''Series/StargateSG1'' likes to play dumb and joke around, but gets things DONE. Also, his irreverence and jokes frequently annoy the Goa'uld and their Jaffa, who are infuriated because Jack doesn't take them seriously. This is, possibly, his intention, although it fails to work on Ba'al.
