Dr. Alien (1989)

Synopsis: This comical, erotic sci-fi adventure is every nerd's fantasy come true as it tells the story of ultra-geeky Wesley Littlejohn who readily volunteers to participate in his voluptuous substitute biology professor Ms. Xenophia's (an alien from outer space) extra credit research experiment. Once in her lab, Drax, her faithful assistant jabs him with a needle and suddenly wimpy Wesley becomes the campus stud-muffin and finds himself surrounded by cooing crowds of scantily clad coeds.
