Brilliant film, but tends to be over looked in favour of the Naked Gun and Airplane! movies. I wouldn't really say it's a slow starter, just that once it hits its stride it's consistently funny. And loads of quotable lines...
"Wait, you've dropped your phony dog poo"
"What phony dog poo?."
"I know a little German, he's sitting over there"
"Nick, I've tried everything: the embassy, the German government, the consulate. I even talked to the U.N. ambassador. It's no use, I just can't bring my wife to orgasm"
"Is this the potato farm?"
"Yes, I'm Albert Potato"
