In no particular order. Also, they might not be the best ones, but they are the ones I've rewatched more than the others.
BB, PK, ZNMD, YJHD, Holiday, Drishyam, Bol Bachchan, Singham, JTHJ, Fukrey, Vicky Donor, Bareilly Ki Barfi, Stree, Badhai Ho, Housefull, Sultan, Special 26, Barfi.
Sad state of affairs that I can't name 20 films even. Some are in my mind like CE, Kick, Dangal, etc. but I don't like them enough.
