Spring Breakdown is a comedy with Amber Tamblyn, Amy Poehler & Parker Posey.
VID 1: Amber Tamblyn is playing a nerd who "goes wild" while on vacation in Spring Breakdown. Here she is lesbian kissing Sophie Monk, I believe, in front of a large crowd as "Sweet Cherry Pie" by Poison plays in the background. Also, Amber dances sexy and gets sprayed with water splashes in a Wet T-shirt contest. Includes slo-mo sections.
VID 2: Amy Poehler in various scenes looking sexy, but silly (nice abs, though). In one part she acts as dance coach to some teens. She instructs them and says, "Heads up tails back... Give me 4 Booty round-a-bouts in unison with extra Butt Cheek vibration. Go!" Also, look for actress Missi Pyle (of Galaxy Quest). Includes slo-mo sections.
