Tarz & Jane, Cheeta & Boy (1975) PG-18

The flimsy plot for this uproariously breezy'n'cheesy porno dazzler has poor Tarzan (cheerfully overplayed by prolific 70's drive-in picture perennial Patrick Wright, who sports a really obvious fake wig), depicted here as an absolute feather-headed goofball who's all brawn and no brains, suffer a hilariously nasty run-in with a ravenous crocodile: the flesh-chomping lizard bites off Tarzan's manhood (ouch!) when Tarz wrestles the beast in a river. So Tarzan, his ditsy, oversexed distaff companion Jane (an endearingly daffy Tallie Cochrane, Wright's real-life wife), and their lunkhead son Boy (some vacuous California surfer dude type who calls himself Uncle Tom) embark on a perilous pilgrimage to Wango Wango Land in order to get Tarzan another penis.
