This is Spinal Tap
The Producers (original)
Buffalo 66

[OwlKaMyst]

There is something to be said about the older comedies.
Murder By Death and The Producers....and...
Can't go to wrong with Mel Brooks or Monte Python.
Blazing Saddles, High Anxiety, Space Balls, MP & the Holy Grail.
Spinal Tap has it's 'siblings' that are equally funny, Best in Show, and, A Mighty Wind.
Blues Brothers, Caddyshack, Airplane, (etc) of course.
The Toy (Richard Pryor)
Real Genius (Val Kilmer)
See Spot Run (David Arquette)

In general, if anyone asked me for suggestions for a "hysterically funny comedy" my mind wouldn't go to anything in the last several decades.

I hope some day you'll get a chance to be near a theater doing a series of 1930s-1940s comedies.
