The duck was the hardest and longest I'd ever laughed in my entire life
I saw this on HBO in the mid-90s and I will never, ever forget the moment that duck mascot gets knocked off the parade float and into a pile of garbage cans. I swear to god I was laughing on and off (basically any time that moment ran across my mind) for HOURS well into that evening. I had trouble getting to sleep because I'd be lying there in bed and think about that big flying foul-mouthed duck and I'd start laughing all over again.
I saw it again recently and while I can't say I was put into an hours-long laughing fit this time, it was still pretty freakin' hilarious.
