It's nice to run across a video feature that, like Debbie Duz Dishes, has a real sense of humor, so we get some wit along with the sex. The "F" in Doctor F could stand for funny; here's a story that doesn't take itself seriously and there's no reason why it should. Doctor F is loaded with slapstick silliness and assorted schtick that keeps you interested even when the sex doesn't. Mike Horner does a wonderful Jerry Lewis nutty professor routine that carries the plot along smoothly. He plays a university researcher who's hired by teen sexpot Careena Collins to invent a potion to give her eternal youth. She's already 18! Instead, the bumbling Horner comes up with a lust potion that turns him into the super stallion known as Doc F.

The tape has great couples' appeal, since the potion turns Horner into one of those male stripper types with the bow tie, the specs, and the french cuffs (played by another actor), who manages to dance even while he's getting his ticket punched. Careena Collins, who is heavily featured here, is perfectly okay, but the show is stolen by Buffy Davis, who turns in one scene that's hotter than the rest of the sex footage combined. Dynamite! Too bad she doesn't get more exposure.

There are a lot of cute video special effects and no real technical problems. The Lust Potion of Doctor F combines a nice story and hot sex into a juicy elixir of lust. Go ahead and drink up.
