Get out the tanning oil, dance leotards and diaphragms because summer camp is in and the hormones are raging.

The new trailer for Netflix 's "Wet Hot American Summer: First Day of Camp " has arrived, and is full of glorious moments. There's Amy Poehler's Susie losing control, Bradley Cooper's Ben in a one-shoulder metallic leotard, Paul Rudd's Andy and Marguerite Moreau's Katie doing some hip-gyrating, Elizabeth Banks' Lindsay borrowing Nurse Nancy's diaphragm and lots and lots of sweaty sexual tension.

But that's not all! The trailer gives us the first look at new cast members like Jon Hamm , who gets in a knife fight with Christopher Meloni's Gene, Kristen Wiig looking for a "cock swing," John Slattery, "Weird Al" Yankovic, Jordan Peele, Michael Cera, Josh Charles, Chris Pine, H. Jon Benjamin, David Wain and Lake Bell. And apparently Ronald Reagan, as portrayed by Michael Showalter. Camp starts on July 31 at 3:01 a.m. ET on Netflix.
