If you’ve seen Judd Apatow‘s This is 40, you know that Megan Fox‘s character Desi co-owns a boutique with Leslie Mann‘s Debbie, and she likes to use the shop after hours for some interesting recreational activities. Fortunately, there’s a security camera to catch every clothed detail.

In this exclusive clip, Apatow and Fox talk a bit about filming the scenes within the scene. It’s as educational as a home-done rectal examination. Plus, Fox finds Apatow’s sex directions and Charlene Yi’s walking in circles absolutely hilarious. Which is strange, because the funniest thing about this is Bill Hader‘s hat. This is how comedy gets made, people.
