Haven't seen a lot of comedy movies, so I might be missing out on some of the best and the 'must-watch' ones, but here are my favourites so far:

1. The Dictator
2. The Hangover 1-3
3. 21 and 22 Jump Street
4. Spy
5. Tenacious D in The Pick of Destiny

I know you're probably asking to pick only one film but, oh well 😄
