See No Evil, Hear No Evil
Grabbers
Kung Fury

Elf.

Lots to agree with here but I can’t believe I don’t see Snatch anywhere.

Not a movie but every few years I do a rerun of Scrubs (but not the last season).

Mr Bean making a sandwich, in particular the person laughing at 3:53

I love White Chicks also, one of my top movies along with Mean Girls and Bridesmaids

Tropic thunder

Penguins (of Madegascar): The Movie is the funniest film ever made and infinitely quotable.

I'll just second OP and say that my girlfriend keeps watching that real shit over and over to the point that we can almost act out the entire thing.

The Other Guys

Lego Batman. If you haven't seen it, go; go now.

It's a Mad, Mad, Mad, Mad World leaves me in stitches every time.

hot shots part deux

Bowfinger

Sean of the Dead and Clerks.

Superbad. Airplane

I watch both VERY often and still love all the jokes

Without a paddle. I haven't seen it in a few years but I remember just absolutely cracking up over it.

The House Bunny

The Return of the Pink Panther

Most of my favorites have been mentioned, but I haven't seen The Party (1968) or Clue (1985) mentioned yet.

Austin Powers. Introduced my dad (who bears a striking resemblance) to it and we had a right laugh watching together

The Court Jester.

Hotel Paradiso

White Chicks as well. Total classic in Brazil since release.

Platoon

The Incredible Bulk.
