Amy Poehler Gives Jay Leno A Townie Tongue-Lashing (VIDEO)

Leave it to Amy Poehler to be utterly charming while swearing someone out in a Boston accent.

While we loved her story about never being on camera at the Golden Globes despite sitting next to Brad Pitt (like she does every year), not to mention her insights into the healing properties of the common onion, it was when she broke out a thick townie accent to call Jay a "f***ing a**hole" that had us, and the in-studio audience, howling.

It was such a great moment, in fact, that it probably got a thumbs up from 'The Tonight Show's' colleagues across the aisle, Team Coco... but for different reasons, of course.
