William Shatner Cracks Dad Joke For His 92nd Birthday

The 'Star Trek' actor proves you can tell a dad joke at any age.

William Shatner is keeping the Star Trek spirit alive on his 92nd birthday. 

The actor turned 92 on March 22, and so, he took to his Twitter account to thank everyone who wished him a happy birthday on his "special day." He also cracked a joke that all Star Trek fans will love and appreciate.

"Thank you for the wonderful outpouring of love and well wishes for my special day today! If we were in the mirror universe; today would be my 29th Birthday! Let’s go with that," the legendary actor quipped.

Fellow actors and celebrity friends previously wished Shatner a happy birthday, and some even shared hilarious stories along the way. 

"HAPPY 92nd BIRTHDAY to William Shatner, the absolute coolest dude I've ever worked with. I wrote his standup monologue for 'Gotham Comedy Live' and when I asked if there were any subjects I should steer clear of he said, "Kid, I'm 85 and I don't give a f--k." AMEN," Jimmy Failla tweeted.

Diedrich Bader, best known for his role on The Drew Carry Show shared his wishes alongside a photo of him dressed in drag while standing next to Shatner.

Actor Vincent D'Onofrio also wished the actor a happy birthday.

The Star Trek Twitter account even chimed in with Birthday wishes, writing, "Join us in wishing a very Happy Birthday to @WilliamShatner! In celebration, share your favorite Captain Kirk moments. #StarTrekFamily #StarTrek."

Actor Elias Toufexis wrote, "Happy NINETY-SECOND BIRTHDAY to fellow Montrealer, the legend that is @WilliamShatner Here is a picture of me with my mind blown because I’m next to him when we both received an award a few years ago. Every time I’ve seen him, he’s always been a gentleman. Happy 92nd!!"

Ahead of his 92nd birthday, Shatner opened up to Variety where he spoke about his perspective on life and death.

"There was a time when actors, and I include myself in this, would portray death by falling to the ground and your eyes would flicker and you’d slump around and then you’re dead," he said.

"That’s not how you die. This is how you die," he said before his eyes went wide and his breathing abruptly stopped. "See? I’m dead. Ever put a dog down? When I have to put a dog down and I’m at the vet, I cup my dog’s head and I say, 'I’m with you baby, I’m with you.' And the injection goes in and the dog looks at me with love, and that’s it. You don’t know they’re dead. That’s how you die. It’s abrupt."

He continued, "My wife’s brother walked out of the living room and into the bedroom. There was a thud. His wife walked in, and he was dead. Death comes anew to all of us."
