Tons of gore, tons of fun, hard to beat the lawnmower scene.
Cannibal! The MusicalCannibal! The Musical

Hilarious horror movie from the director of Animal House.
Shaun of the DeadShaun of the Dead

The laughs don't start coming until bodies start to come back to life, but they are decent laughs.

Amazing trilogy, if you wanna have a lot of fun, buy a case of beer, invite your friends over, and watch these movies.
The Rocky Horror Picture Show (Widescreen Edition)The Rocky Horror Picture Show (Widescreen Edition)
Buy new: $10.49 / Used from: $3.90
Not really a "horror" movie by most people's standards (it has SOME horror elements, there are zombies and aliens), but it is a really good movie, with plently of laughs and great songs.
Evil Dead IIEvil Dead II
Buy new: $11.99 / Used from: $2.00
Wacky Bruce Campbell fun, I'm sure anyone reading this list has seen this movie or own it already (at least I hope so).
Army of Darkness (Boomstick Edition)Army of Darkness (Boomstick Edition)
Buy used from: $19.96
Sequel to Evil Dead movies, Evil Dead II is better, but this movie isn't bad at all.
Bubba Ho-Tep (Limited Collector's Edition)Bubba Ho-Tep (Limited Collector's Edition)
Buy new: $14.99 / Used from: $1.88
Not really too funny of a movie, but definitely worth watching, especially if you are a Bruce Campbell fan.
Killer Klowns from Outer SpaceKiller Klowns from Outer Space
Buy new: $11.99 / Used from: $2.26
Hilarious movie about alien clowns who turn people into cotton candy and drink them through straws.
Attack of the Killer Tomatoes - Special Collector's EditionAttack of the Killer Tomatoes - Special Collector's Edition
Buy new: $22.49 / Used from: $7.84
If you can put up with the low budget crappiness of it, its hilarious, but then again, the low budget crap is often what makes it funny.
Bad TasteBad Taste
Buy used from: $13.91
Again, if you can deal with low budgetness, its good.
Critters 2 - The Main CourseCritters 2 - The Main Course
Buy new: $13.49 / Used from: $3.86
If you want to see any Critters movies, watch this one, its the best. This is the one where the critters form a giant ball and run people down. Plently of other funny moments as well.
Ghoulies/Ghoulies 2Ghoulies/Ghoulies 2
Buy new: $11.99 / Used from: $4.79
The second one is definitely better than the first one, but you have to have a lot of patience to watch either of them. If you want to give them a chance, good for you, you might like them.
Friday the 13th, Part VIII - Jason Takes ManhattanFriday the 13th, Part VIII - Jason Takes Manhattan
Buy used from: $2.75
This is my favorite Friday the 13th movie, its definitely the funniest.
Cabin FeverCabin Fever
Buy new: $9.98 / Used from: $0.89
This movie is "alright." It has a few moments here and there, it's definitely worth the $1.50 used price, but don't pay more than $5 for it.
KilljoyKilljoy
Buy new: $19.98 / Used from: $12.99
This movie is pretty damn stupid. You might get a laugh at just how bad it is.
Citizen Toxie - The Toxic Avenger IV (Collector's Edition)Citizen Toxie - The Toxic Avenger IV (Collector's Edition)
Buy new: $13.49 / Used from: $5.00
This movie was pretty funny, I have a friend who loves Toxie, he tells me that this one lacks the "heart" that the 3 before it had. I can only vouch for this one, its the only one ive seen.
Bloodsucking FreaksBloodsucking Freaks
Buy new: $17.99 / Used from: $9.91
If you don't get offended by obviously perverted torture stuff, then this is quality. This is way better than that crappy Hostel garbage.
Redneck ZombiesRedneck Zombies
Buy used from: $12.65
Bad camerawork, bad acting, bad story. In horror comedies, that equals good stuff. If the used price ever goes down to like $5, its worth it.
Death Race 2000 - Special EditionDeath Race 2000 - Special Edition
Buy used from: $18.29
More of an action movie than a horror movie, but plently of gore and blood, and even more laughs. Stallone punches a chick in the face really hard in this movie.
The JanitorThe Janitor
Buy new: $9.98 / Used from: $4.95
this movie is very, VERY funny if you are down with this kind of sick humor. It is a horror movie that actually tries to be a comedy as well (it is self-aware of its stupidity) and actually succeeds!
