Jon Hamm was featured in a funny segment in Jimmy Fallon's "Tonight Show." The segment featured the duo in a non-existent show entitled "Palisades Park Pet Patrol," where they played as two animal patrol officers.

The best part with this segment with Jon Hamm is that they had to constantly stuff their faces with food only to spit it all over each other as they kept arguing. Although they are portraying the roles of animal patrol officers, there were absolutely no animals present during the segment.

Loyal fans of Jimmy Fallon might remember that this hilariously funny talk show host did a similar stunt with Alec Baldwin just last year in his previous show, "Late Night."

Jon Hamm and Fallon were not choosy in the food that they packed their mouths with. From loads of whipped cream to glasses of fruit punch, they were never shy in attempting to cover the other with whatever it was that they chewed in their mouths. During their pretend argument, they said a lot of words that started with the letter "P," which is most likely the biggest reason why they ended up spitting. Fallon had to contend with a fake mustache that kept falling off.

Jon Hamm is actually a long-time friend of Fallon's in real life. During his interview in the show, he mentioned that he is presently occupied in the filming of his new TV show, "A Young Doctor's Notebook." This new show will be featured on Ovation, and he will be working with Harry Potter himself, Daniel Radcliffe.

According to Jon Hamm, he will be playing an "older version of him that only exists in his mind." Fallon showed the audience a short video clip from Jon Hamm's new show, and Jon Hamm was shown dancing the waltz with Radcliffe while they were talking about the younger doctor's love life.
