The Willies (1990)

Sean Astin post-Goonies and pre-The Lord of the Rings. Things start out with three kids having a campout in their backyard telling grosser than gross jokes, talking about urban legends (like a woman who gets a rat in her bucket of fried chicken/why Disney Land’s Haunted Mansion isn’t scary), then leads into two main stories. Definitely more campy than scary but a fun watch nonetheless.
