Yeah - I like Stew's list too! Particularly Midnight Run at number 1
Also liking Planes, Trains... cropping up in a few lists, I love that film. Has a big heart.
In no particular order my 5 today would be:
Midnight Run
Team America
Borat
Planes, Trains and Automobiles
Elf
Airplane and Naked Gun should be in there too though.
