Teachers and Cream (1973)

"To Whom It May Concern, Good Bye!!! Yours Truly, Anonymous," reads the suicide note English teacher Mr. Boynton writes and tapes to his chest. Dejected because he’s going to lose his job for moonlighting in porno flicks, he also wears Groucho Marx glasses (you know, with the big nose and fake moustache) which, somehow, is necessary apparel for someone about to jump off a New York City bridge. But before he leaps, he is rescued by a student of his named Nancy and Miss Crabtree, the Phys. Ed. teacher. As thanks for saving him, the gals go with him to "an editing room" and double-team him.
