It (1990) and Patch Adams (1998) come to mind.
Airborne is hilarious. Twister is pretty good too.
Jaws III is also hilarious.
The Room (2003) is up there as well.
Shark Boy and Lava Girl is a hilarious review. The 2016 Commercials special might be the best of the bunch.
His A.I. (2001) review had me laughing so hard I couldn’t breathe at one point.
