A pregnant Christina Applegate has demonstrated her dedication to her craft by strapping on some stripper heels and swinging around a pole -- all for comedic effect. In a new skit for Funny or Die, the 39-year-old actress poses as Roxy Fedaro, a dance instructor selling an instructional prenatal pole dancing DVD. Watch as she struggles to touch her toes and falls off the pole -- ha-hah! Silly pregnant lady trying to be sexy. There are also jokes about farting and hemorrhoids. It's a reminder that while we like seeing pregnant celebrities naked, we aren't ready for them to act sexy (unless, of course, that's your thing).
