I continuously struggle with how I enjoy comedy. On a basic level, I find some a gag, a slapstick, a one liner just as funny as anyone else, but on a long term level, I don't have the same opinion on a comedy after time passes as I did the first time. Watching a comedy a second time mostly ruins some sense of nostalgia I had previously. But here are some comedies that I have watched at least twice and still thought it just as funny.
I don't enjoy crude and offensive humour as I used mainly because most comedies just want the shock value, cursing just cursing's sake isn't that funny to me.
