for me personally
1. Steve Martin (his sense of humour has always remained the same levels of genuine classic comedy, quite a diverse talent he is as well, from CBTD films to playing Inspector Clouseau on Pink Panther or nowadays in OMITB as well as his parody of MJ song Billie Jean or his original song King Tut)
2. Bryan Cranston (while breaking bad isn't exactly my cup of tea, Bryan on the other hand, i absolutely LOVE watching him, especially in Malcolm in the Middle, his sense of humour is so quirky, wacky and so iconic)
3. Phill Lewis (shame after his DUI incident he isn't doing much acting work anymore nowadays but Marion Moseby in suite life is one of my all time fave sitcom characters, high up there with John Cleese's Basil Fawlty tbh, that type of comedy is soooo my cup of tea)
4. John Cleese (Basil is the GOAT in Fawlty Towers, and **** Cancel Culture since he really slayed hard in that role, i also liked him in Bond as the new Q in the world is not enough, die another day)
5. Robert De Niro (especially in Meet the Parents, Meet the Fockers he is the king of comedy! that chemistry he had with the likes of Dustin Hoffman, Barbra Streisand in the latter of the two

also YOU TALKIN TO ME is one of the most epic one liners from him)
