Love Potion No. 9 (1992, D: Dale Launer, W: Dale Launer)
This one falls squarely in the Guilty Pleasure category because, for some time, it was always on cable. And if it was on, I wound up watching it. More than a couple times. I feel funny even telling you this. I have no rational explanation whatsoever. Tate Donovan invents a love potion. Sandra Bullock has bad hair. The end.
