What part made you nearly poop your pants laughing?
For me it was the Winnebago scene(specifically when Champ is falling back and the dog jumps up and bites him for no reason and the scorpion pinching Ron, of course)and the dramatic and beautiful song dedicated to Doby the Shark later in the movie.
Dick Phuk got a pretty big hearty laugh out of me as well, but I don't think it made me have to pause the movie and change my underwear like the other two scenes did hahaha
DID YOUR ASS GET ENOUGH WINGS?!
