Watch Grace Star Paul Rudd Take Viagra & Eat 'Special Brownies' in This Is 40 Trailer

Remember Pete and Debbie from Knocked Up? They’re back in This is 40, a much-buzzed-about new comedy by Judd Apatow. In the new spin-off movie, Pete (Grace star Paul Rudd) and Debbie (Leslie Mann) try to spice up their sex lives, wrangle their two kids (played by Apatow and Mann’s real-life children, Maude and Iris) and of course, eat pot brownies while crawling around on the floor of a swanky hotel.
