I'd have to say Dumb and Dumber. After what.. 12 years its been out? i still crack up watching Lloyd pull up to the Austrian girl at the beginning of the film.. "Mmmmm... Austrian!?"

Other ones that came to mind were
Bruce Almighty
Scary Movie 3
Ace Ventura 1, 2
Laurel & Hardy ("Here's another nice mess you've got me into!") LOL
Aladdin (yea Disney... so what) was fuckin jokes as well
Mrs. Doubtfire
Billy Madison
Waterboy
Happy Gilmore

Dude... no place in town has Billy Madison on DVD... wtf!?

my faves are
billy madison
eddie murphy raw/deleriouse
shaun of the dead

best movie of all time which is sort fo a comedy : ferris buellers day off

best strict comedy of all time : holy grail...

Monty Python and the Holy Grail is so great...the whole Black Knight scene is hilarious ,as is the tale of Sir Robin, which goes something like this:

"Bravely bold Sir Robin
rode forth from Camelot
he was not afraid to die,
Oh brave Sir Robin.
He was not it at all afraid to be killed in nasty ways,
Brave brave brave brave Sir Robin.

He was not in the least bit scared to be mashed into a pulp
Or to have his eyes gouged out and his elbows broken
To have his kneecaps split and his body burned away
And his limbs all hacked and mangled
Brave Sir Robin

And his head cut off
And his nostrils raped
And his liver removed
And his penis...

...Brave Sir Robin ran away
Bravely ran away away.
When danger reared its ugly head
he bravely turned his tail and fled
Yes, brave Sir Robin turned about
And galantly he chickened out
Bravely taking to his feet
He beat a very brave retreat
Bravest of the brave...Sir Robin!"

I don't know about my favourite comedy ever though.

Holy Grail
Naked Gun
Blazing Saddles
Happy Gilmore
Anchorman
Ace Ventura
Clerks
Zoolander

All of the above i can watch over and over, but i just watched anchorman tonight and gotta say that will ferrell is absolute class.. didnt think he could top his performance as "frank the tank" in Old School... Brilliant!

LMAO... i just watched frank the tank... that movie is fukin jokes (old school)

"everybody we're streaking!"

Naked Gun Trilogy
Dumb and Dumber
Planes, Trains, and Automobiles
Tommy Boy
Meet the Parents
Not Another Teen Movie (Yes, really.. I crack up at their jokes)
Zoolander
Jay and Silent Bob Strike Back

i was really surprised when not another teen movie came out and everyone hated it... i really liked it as im big into 80's teen movies, todays teen movies suck balls...

i was esp surprised as a lot of people make themselves out to be big into the 80's stuff (from transformers to the breakfast club)... i bet those people didnt get at least 60% of the references... dah well we all new they were posers anyway...

Airplane 1&2
Naked Gun trilogy
