Legendary director, actor and producer Garry Marshall is dropping by The Odd Couple -- and it promises to be a memorable time!

The 81-year-old New York native, who created the original ‘70s sitcom (and later the ‘80s series), takes a turn in front of the camera on this Thursday’s episode of the CBS reboot, and ETonline has your exclusive first look.

Marshall doesn’t miss a beat as Oscar’s (Matthew Perry) father, who visits his son after Felix (Thomas Lennon) decides to call him up after Oscar gets the opportunity to throw out the first pitch at a New York Mets game. Though Felix’s intentions were good, Oscar’s not exactly thrilled about his pops’ unexpected visit.

“Playing Oscar’s father, I guess I’m the right age now,” Marshall said, before reflecting on his time on the Jack Klugman-Tony Randall comedy in the ‘70s. “I acted a little on the old Odd Couple but I didn’t play anybody’s father.”

Odd Couple co-star Yvette Nicole Brown marveled over being in Marshall’s presence and admitted that she had one hope.

“My only request was to have a scene with him and I threatened to quit if I did not,” the actress shared.

Thankfully, she got her wish!

For Perry, acting alongside Marshall, who directed the upcoming film Mother's Day, was a real plus. “They have that father-son thing where [Oscar]’s constantly seeking his father’s approval and Garry’s such a lovable guy that everybody else in the cast loves him and that really frustrates Oscar,” he said of Marshall’s presence.

Lennon shared the deep impact Marshall has had since childhood.

“For me, I was raised by all of his TV shows,” Lennon said. “Don’t tell my parents this but I was never happier than to be left home with a babysitter and a Salisbury steak frozen dinner and watching Happy Days and Laverne & Shirley and Mork & Mindy, and everything that has come out of his mind.”
