 If you liked Osomatsu-san |  ...then you might like Saiki Kusuo no Ψ-nan |
As for Osomatsu-san there is no story as a whole, I think it's important that its recommendation is not just another anime with comedy. For Saiki Kusou is somewhat the same, there is no story outside of comedy to develop. It doesn't switch between comedy and story. It's just for comedy.

Osomatsu-san has 6 sextuplets as main characters, while Saiki K. has 1, with a lot of the supporting cast. - Both are hilarious (given) - Both makes lots of references to different animes/manga - Both lean more on dialogue/narrative comedy
Both has a wacky cast with satirical/light hearted humor. Osomatsu has longer episodes, and also has a lot of references, just like Saiki. Osomatsu has a eccentric cast with characters with flaws, just like Saiki.
