Liev Schreiber knew something was up on Friday when the comedian asked the actor about a recent visit to the San Diego Zoo.
"You tweeted some nice photos," Fallon praised before teasing the actor, who was on the show to promote the new season of "Ray Donovan." "I just didn't know that the San Diego Zoo was full contact. I just didn't understand that you can make out with a giraffe!"
As Schreiber's tweets revealed, he really got up close and personal with Behati the Giraffe. "She liked me!" he told Fallon.
Fallon wasn't done poking fun at his guest yet, though. He also managed to get the Emmy and Golden Globe nominated actor to share not one, but two "embarrassing" tales about how Schreiber had his nose broken.
"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. on NBC. "Ray Donovan" kicks off season two on Sunday at 9 p.m. on Showtime.
