I agree with Dan’s statement that Dumbo is one of Disney’s better films—although Pinocchio is still the best by far—and here’s the best scene from that film:
Really, it is to Dumbo what Pleasure Island is to Pinocchio. This scene really pushes it over the edge, and without it, it wouldn’t be half as good.
EDIT: As an avowed and proud alcoholic, I can officially state that that was not just alcohol. I have no idea whether it was mixed with cannabis, LSD, or what, but it wasn’t just alcohol.
