It has everything, including an all-star cast that I don't believe will or can ever be duplicated EVEN WITH, obviously, current comedic actors.

Some I others I love:

M*A*S*H - the movie, and TV show.
Some, not all, of the old Laurel & Hardy Movies - also Abbot & Costello
All the Monty Python Movies
Airplane
Spaceballs
Raising Arizona
The Producers
