This One Time, Chris Pratt Showed Amy Poehler His Penis

Here's a workplace tip: Don't show one of your co-workers your penis.

That should be obvious, but when you're Chris Pratt and you're on the set of "Parks & Recreation," sometimes it doesn't seem that black and white.

The "Guardians of the Galaxy" star revealed a prank he pulled on "Parks" co-star Amy Poehler during a chat with Seth Meyers. As the story goes, Pratt (playing the generally clueless Andy Dwyer) was supposed to show up on Leslie Knope's doorstep, naked. Of course, when those sorts of scenes are done and the end result will be blurred, flesh-colored briefs are usually used.

But Pratt felt that he wasn't getting the right reaction out of Poehler. She just wasn't horrified enough, perhaps?

Pratt's plan: Show up at the door during the next take completely naked.

As Pratt explains, pretty much everyone told him that would be a bad idea, and sure enough, he did get in some serious trouble for it. But as you can see in the clip, he did succeed in his end goal of getting an appropriately horrified expression out of Poehler.

And by the way, that take is the one they ended up going with.
