Almost Pregnant(1992)

Charlie (Conaway) is a happy man with a beautiful wife (Roberts), a wonderful career and every blessing a man could want except "...children". When the wife demands a "star child" and Charlie can't deliver the goods, they turn to their crazy neighbor (Calvin) to get the job done, so to speak. Very hilarious and bawdy comedy where "one rooster to a hen-house" is not always the truth.
