Airplane pretty much started..well made these types of films more well known. I love these types of films. Some are more creative than your typical Oscar nominees..they always get unnoticed...tisk...tisk. These are my favorites :p
Awesome to see Kung Pow! up there. LOVE that movie.
Since you obviously dig the Zuckers & Abraham's work, you might check out The Kentucky Fried Movie. It's the first film they wrote together, a little dated now but pretty hilarious still.
I'd also check out "Brain Donors" if you like the Zuckers. Basically they got Pat Proft to write a Marx Brothers comedy and put John Turturro in the lead. It's brilliant.
Wow I actually contributed to a list that wasn't mine! I loved Top Secret! when I was younger but the only problem I have with it is that it doesn't actually have an ending. Maybe they took the spoof so far as to spoof all movies that have a happy ending and then not even have one. I don't know.
