Not surprisingly, that scene didn't play out as originally scripted. Venkman was originally supposed to give the “I hate Jell-O” line.

I will feel bad the day that all this board has come down to is quoting the lines from the movies. Oh wait thats today.

No offense but after that part in the movie I haven't been able to eat jello after that.

Jesusfreak, you reminded me of that time on “The Simpsons” where Bleeding Gums Murphy was on The Cosby Show–

Cosby: Hey kids! Meet Grandpa Murphy!
Kid: We have three grandpas already.
Cosby: This one's a great jazz musician!
Kid: Oh, they all are!
Cosby: Ooh, ooh – you see? The kids, they listen to the rap music, which gives them the brain damage. With their hippin' and the hoppin' and the bippin' and the boppin' – so they don't know what the jazz – is all about! You see, jazz is like Jell-O pudding pop. No! Actually, it's more like Kodak film. No! Actually, jazz is like the new Coke! It'll be around forever. Heh heh heh.
