The Tonight Show Starring Jimmy Fallon

"I think it's if not the best, one of our best episodes ever," revealed the Chicago P.D. star.

The One Chicago star joined Jason Beghe and S. Epatha Merkerson for a pre-finale chat on The Tonight Show Starring Jimmy Fallon. 

"A little bit about me: I love opening a fresh jar of organic peanut butter just so I can guzzle the oil on top."

Their story involves Fred Armisen, a Paul Weller concert, and a friendship that dates back to Fallon's Saturday Night Live days.

The British heartthrob had quoted Samuel L. Jackson from the original Jurassic Park in a foreshadowing Instagram post.

Mariah Carey, Tina Fey, Joan Rivers, and more stars ponied up during Fallon's 2014 Tonight Show premiere.

The rapper told Jimmy Fallon he's excited to say "Hay!" to Mopsie, a.k.a. "Rave Horse."

Snoop Dogg's so ready to join his friends Gwen Stefani and the gang as a Season 26 Coach.

"She comes across with a paper plate full of whip cream and slaps me hard across the face," Fallon told Willie Geist on Sunday Today.

The two friends had lots to reminisce about in their look back at filming the 2005 Red Sox romantic comedy.
