The Wallflower(1941)

A homely old maid hen with buck teeth tries to get a boyfriend at an all-chicken barn dance. The only one she's interested in is a cornball practical joker in an old-fashioned straw hat, who returns her affection with embarrassing dirty tricks. When she's in an egg laying competition, he slips her some gum that causes her to lay a bursting, gooey balloon, and he tricks her into eating hot pepper-laced ice cream. She finally becomes the belle of the affair when her pepper-infused smooching is a hit at the kissing booth.
