Dick Van Dyke astounded fans with his TV appearance on Jimmy Kimmel Live on December 5, ahead of his 99th birthday.
The adored star joined Coldplay's Chris Martin for a joint chat and their connection was amazing to watch.
Dick — who appears in the group's "All My Love" video — stepped onto the set looking dapper in a black suit and walked with the aid of a cane.
Chris followed in similar attire and they waved to the cheering audience.
But as Dick went to sit down in his armchair, he stumbled. Chris quickly dashed to his side and helped ease him into his seat.
Jimmy made light of the moment as he welcomed his guest by saying: "You even stumble elegantly," before asking "How are you?"
Dick laughed off his not-so-fancy footwork and smiled for the host and the audience who continued to applaud the duo.
Chris was full of praise for Dick, who he confessed he's been a long-time fan of.
Talking about the music video which stars Dick dancing barefoot at his Los Angeles home with his family, Chris confessed: "I think it's the most fun thing I've ever done. It makes me so grateful."
Chris recalled one of his favorite moments from filming when Dick's children and grandchildren were all around.
He said he loved watching Dick's son, Barry, "who is 74," catching the attention of his dad, and gently asking: "Dad, could I put the pool slide on?"

Dick laughed at Chris' story before admitting, he has another son who is 78, "and I'm old enough to be Joe Biden's dad."
Chris also revealed he's probably watched Mary Poppins close to 55,000 times, while Dick said it's been a while since he viewed it himself.

Jimmy quizzed Dick on his birthday plans and he quipped that he'll probably just "hide out."
Dick elaborated and said while he didn't think he'd have a party, he said: "My kids will probably all come over though."
Jimmy asked Dick his secret to longevity, to which the Diagnostic Murder actor said: "What's the secret? I don't know. I have no idea," before adding: "I still exercise. I go to the gym. I think that has something to do with it. Keep moving. I wrote a book 'Keep moving.' The older you get the more important it is."
