Mary Ann wakes up alone in her grass hut. Who knows where that slut Ginger is off to again? She could be sleeping with the Professor, Skipper, Gilligan, or even Mr. Howell!. She slips out of her hut, wearing nothing but the jean shorts and gingham shirt she was marooned with (plus inexplicably several other outfits for a 3 hour cruise). The first hut she comes to is the Professor's. Good, he seems to be alone. Maybe Ginger has Gilligan balls deep. She slips in and slides into the cot with the Professor. Let's see what he really has to teach.
