Best comedy movies consisting completely of jokes

Comedy movies with no dramatic breaks, just full on comedy. For example, The World's End is one of my favourite and funniest comedy movies, but it gets really dramatic at some point. Here are some examples of what I want:

-Dr. Strangelove (my 2nd favourite movie of all time)

-Monty Python’s Life Of Brian (consists completely of jokes but still very emotional, you'll know what I mean if you've seen it)
