Cannibal Women in the Avocado Jungle of Death (1989)

Synopsis
Buxom Playboy foldout Shannon Tweed plays a sexy college professor assigned to investigate a sudden, disastrous avocado shortage; her predecessor, a Dr. Kurtz (Adrienne Barbeau) has never returned from the dreaded California Avocado Jungle. Accompanied by air-headed assistant Karen Mistal and macho guide Bill Maher (of Politically Incorrect fame), Tweed ventures into the deepest jungle, where the Piranha Women rule. Proof that this civilization is a matriarchy is the presence of a tribe of wimpy, domesticated men called the Donnahews, who chant names like Alan Alda and Fritz Mondale as their mantra. Fortunately, Tweed is armed with her N.O.W. membership card, so she is allowed safe passage. She finally catches up with Kurtz, who reveals that the avocado shortage is phony, designed by the government as an excuse to capture the Piranha women and transform them into Malibu housewives. ~ Hal Erickson, All Movie Guide
