Woody Allen took some questions from the book of the same name and filmed several segments supposedly relating to these questions. "Do aphrodisiacs work?" is a very funny medieval sketch where Allen winds up with his hand locked in the chastity belt of his horny married queen (an excellent Lynn Redgrave). "What is Sodomy?" actually looks at bestiality as Gene Wilder plays a doctor who falls in love with a sheep. It's a bit yucky, like anything pertaining to the subject, but it has its moments.
Verdict: Watch out for giant boobs! ***.
