Hmm, looks like "Porky's II: The Next Day" was the Shakespeare one. "Porky's Revenge" was #3, and was about throwing a baseball game. I don't recall that one.
But Porky's II had one of the all-time great lines: "Get the flock out of here."
oh well. Porky's II was far and away the best of the three, there's no doubt about that. I also really liked the one in the school office. Quoting from Shakespeare:
Crazy KKK Guy: "'What, put my tongue in thy tail?' Now what kind of a man would do something like that!"
All the boys in the room start jumping up and down yelling "Me! Me! Me!"
