Examples I can think of.... Well, they're often made into animes that only last about 5 minutes an episode. They're also completely bonkers, fast paced, & episodic, with little to no continuity, preferably not slice-of-life. 4komas are a good example. For the hell of it. I'm also including animes. BL & Ecchi are both fine.

*Bobobo-bo Bo-bobo.
*Bokusatsu Tenshi Dokuro-Chan.
*Crayon Shin-Chan.
*Danshi Koukousei no Nichijou.
*Dragon Half.
*DiGi Charat.
*Excel Saga (in this case, only the anime counts).
*Gakuen Handsome.
*Goldfish Warning.
*Hetalia.
*High Score.
*I Love BL Comics.
*Jungle wa Itsumo Hale Nochi Goo.
*Juubei-Chan.
*Mr Andou of the Woods.
*Nekojiru Gekijou.
*Nirvana Mountain.
*Patalliro.
*Sexy Commando Gaiden: Sugoiyo!! Masaru-san.
*Sukigake Cramortie High.

Series that only qualify for half the series. they get way too serious, dramatic, & serial in the second half, but I'll except these as well.

*Onepunch Man.
*Gintama.
*Gokusen.
