In Jennifer Lopez’s frothy comedy The Back-Up Plan (which opens Friday), she’s pregnant by artificial insemination and will inevitably deliver that baby by movie’s end. And if there’s anything we’ve learned from sweeps sitcom episodes and movies like Nine Months and Knocked Up, it’s that childbirth can be a scary process, what with all the panicky dads passing out and the screaming of “GET ME THE DRUGS!” And so, after carefully consulting some of pop culture’s most famous births, we’ve compiled a helpful video slideshow for J. Lo called “What to Expect When You’re Expecting in a Comedy.” And thanks to The Cosby Show and Junior, this tutorial can work for women and men! (Pregnant women in hospital dramas should look elsewhere for tips: having your breach baby delivered by an intern during a snowstorm will not be covered here.)
