For me it's probably Jazzpunk, but I liked Disco Elysium too. I've been looking for something to scratch that "Jazzpunk surrealist comedy itch" for a while and not many games have come even close.
For a game that's a full comedy romp, West of Loathing consistently ruined me with laughter. The spittoon descriptions are probably the most derangedly funny writing ever put into the world. I've got to remember to play the sequel one of these days. Its also extremely mechanically satisfying, with several enticing roleplaying moments (as well as the occasional dramatic or scary moment that hits just as well as the comedy)
For a game that's not explicitly only comedy but still hits strong marks, Yakuza 0 is a full meal. While most Yak games are fairly wacky when it comes to sidequesting (1 being perphaps the single exception, as the beginning of the series was quite dry), 0 feels like the one where they really hit their stride. There's so many flat out ridiculous moments (you've most likely seen the chicken, and that's just one of many) that you even forget this is also a heavily dramatic story and a full blown action beat'em up.
If you liked that it's based on a browser game called Kingdom of Loathing, the gameplay is not as tight or refined but there's plenty to do and it's pretty enjoyable to play when you have some time to kill on a work pc lol.
