Zombie Self Defense Force, http://www.asian-horror-movies.com/zomb.php

For me personally, it has to be Return of the Living Dead

It's pretty obvious that the creators wanted to make the movie funny to an extent, and they did a really great job.

My memory is a little rough around the edges, but I love the bit where that one girl's boyfriend becomes a zombie and he is like "Come on! I love you, just let me eat your brains! Please?" and she eventually comes around like "Fine...you can eat my brains". Then in the very next scene, he is chomping away at her head!

I thought the entire movie was great...maybe even my favorite zombie flick. Although, I typically find nearly all zombie movies good, so take that opinion with a grain of salt.

Shaun of the Dead movie pretty fits the title.

IMO what zombie film is not funny?

That said my top comedy zombies are:
Shaun of the Dead
Fido
Flight of the living dead/ flight of the dead (can't mind the correct title, but I feel it should have been called zombies on a plane anyway lol).

Bubba Ho-Tep isn't a zombie movie in my book. Unless now mummies are classified as zombies. I suppose its a fine line......

Lets just not get started on the differences between zombies and mummies. I fear a black hole may open up and pop, bye bye HDC.

Fido is a great one I thought

Braindead
Fido
Sean of the Dead

Boy eats girl.
ZA
Plan Nine From Outer Space
Tokyo Gore Police (Okey they are technically not zombies but close enough.)
Dead Snow

Got to be Toxic Zombies aka Forest Of Fear though cos it has a pop at the US Government it got banned but its worth tracking down and hilarious :)
