Chris Pratt stopped by Late Night with Seth Meyers on Wednesday night and revealed a secret about filming a scene for Parks and Recreation with Amy Poehler.

Pratt told Meyers NBC actually reprimanded him for what he did and reminded the late night host he’s actually not supposed to be talking about it, but they’re “not going to fire me” because they’re in the last season anyway.

So what is the shocking “method acting,” which Meyers refers to it as, that got him in trouble with the network? He flashed his penis to Poehler during a scene.

E! Online reports Pratt explained it took place during the second season, during which their characters were romantically involved.

Pratt’s character Andy was supposed to show up at Poehler’s character Ann’s house naked in some sort of miscommunication they had, which explains her surprised reaction.

However, she seemed really, really surprised in the scene because Pratt decided to go “trou-down” instead of wearing the “skin-colored briefs” they provide.

Watch him explain what happened and Poehler’s shocked reaction below:
