Rabbit Test is a 1978 American comedy film about the world's first pregnant man, directed and co-written by Joan Rivers and starring Billy Crystal in his film debut.

Plot

Lionel Carpenter (Billy Crystal) is a night-school teacher who has bad luck with women. He remains a virgin until his brash cousin Danny (Alex Rocco) sets him up with a one-night stand. Soon after, Lionel starts feeling nauseated and vomits, eventually doing so onto Segoynia Savaka (Joan Prather), one of his immigrant students. This turns out to be a blessing in disguise, as it gives him an excuse to ask her out on a date, and a romance develops.
