Monty Python episodes from the 60's, and their films, especially Holy Grail.

I got a good laugh from comedian Tom Papa's Netflix special You're Doing Great. Some Like It Hot and Tootsie are two films that are guaranteed to me make laugh no matter how many times I watch them.

Omg Christina ... Sister Michael is everything!!!

Count me among the Seinfeld and Schitt’s Creek fans. Moira’s “Caw! Caw!” Laugh out loud funny, but I shed a tear more than once too.
Central Intelligence with Dwayne Johnson made me giggle.

Late to this but:
Haven’t seen this in a while, so not sure how its hold up, but back in the day 3rd Rock from the Sun always made me laugh (in US I believe it’s available on a number of streaming services, including Prime).
Also, another oldie, Mork and Mindy.....(early seasons only)
hmmmm, i guess i really like fish out of water stores

Movies Calendar Girls and Best In Show.
Old TV reruns of The Carol Burnett Show.

Carol Burnett is one of my most favourite shows ever. It does not get old.

Rachylou - can't tell you how many nights I babysat to Carol Burnett, and Bob Newhart (the older show) and Mary Tyler Moore. AND Sonny and Cher!

Oh I watched all those and was especially enamoured of Sonny and Cher - I watch the reruns of them too, lol
