Ptooey! Jon Hamm and Jimmy Fallon have a messy conversation on 'Tonight'

Jon Hamm and Jimmy Fallon always have a blast when they get together. Remember when they played Water War on "Late Night"? Photobombed tourists together on "The Tonight Show" in March? The laughter was back again when the "Mad Men" star stopped by the late-night show on Friday, but this time, the pair added a bit of grossness to the mix.

In a skit about the "Palisades Park Pet Patrol" ("It's like 'Lethal Weapon' with two Mel Gibsons!" Fallon joked), the two played animal control officers with a major fondness for enunciating the letter P — while talking with their mouths full. Yeah, we bet you can imagine how that went.

As gross as all the flying food was, viewers couldn't deny that the skit was gut-bustingly hilarious.

Fallon himself was pretty pleased with how the show went.

"The Tonight Show" airs weeknights at 11:35 p.m. on NBC.
