Ninety-year-old Dick Van Dyke has had a lengthy career in television, theater and film, but out of all of the projects he's been a part of -- "Mary Poppins," "Bye Bye Birdie," "Diagnosis: Murder," "The Dick Van Dyke Show," "Chitty Chitty Bang Bang," to name a few -- one of them continues to stand out among the rest.
"The five years at 'The Dick Van Dyke Show' were the happiest five years in all of our lives," Van Dyke tells "Oprah: Where Are They Now?" in the above clip. "It was creative, we laughed and joked every day, and there was a lot of improv going on. It was just such fun to do."
