Attack of the 50 foot woman?
This scene came to mind the other day and i have no idea where its from-
So it's at a fairground of some description and for some reason there's a woman who grows really tall and then some kid says to his dad "I wanna go on that ride!" and he says "Me too son, me too", or something like that, as he looks up her skirt.
I think its a film in the 90s. More of a comedy but probably spoofing that. Using that as a baseline, ive found nothing.
