hahah that movie was hilarious! Some one already said this, but it was really funny when their in the backyard throwing shit at the zombies!
I like when they meet up with the other group and they're all standing it symetrical order and wearing the same thing. Its brilliant.
Wow... I didn't expect so many people to watch and to enjoy this movie... Does make me rather happy that people have a similar sense of humour as me.
If you liked Shawn of the Dead, seek out the DVD of "Spaced", the TV series Simon Pegg did before making the film. Absolute genius and very similar humour with lots of film references.
