When the film Porky's came out in 1982 where I saw it in theater, it was a funny movie. And recently watching it on DVD after 30 years, it still make me laugh out loud.
The film is about the escapades of teenagers at the fictional Angel Beach High School in Florida in 1954 trying to score with girls in any which way, and unlike other high school movies it doesn't hold back when it comes to nudity and vulgar language.
The best scene which is probably one of funniest in movie history is where the female gym coach goes to Principal and request a police-type line-up of the boys in the nude so she can identify the penis of a student that she scratched as it was sticking out of a hole in girl's gym shower.
And three guys that were in the principal office kept joking about it untill the prinicipal lost it too and laughed his ass off
