No matter how popular you become, it's always important to make sure that your biggest fan is yourself. If you don't have confidence in your abilities, how is anyone else supposed to?

At 100 years old, Dick Van Dyke has too many decades of incredibly acting under his belt to be anything but confident in his abilities. Van Dyke rose to prominence in the hit television series The Dick Van Dyke Show.

Though the series lasted roughly five years, the mark that it had on television history was enormous. Moreover, the series reaches new viewers every day, with plenty of fans laughing at certain episodes just as hard as when they originally aired.

Of course, Van Dyke was a fan of his own series, and sang the show's praises long after the series ended in 1966.

During an event in Malibu, the actor revealed one of his favorite episodes of all time, "It May Look Like a Walnut!" In this episode, Rob Petrie watches a sci-fi movie, and later believes that the events of the program are coming true. Oddly enough, the episode features a great deal of walnuts, something that both the characters and cast had to deal with.

"That was my favorite," Van Dyke said of the episode according to an article for PEOPLE. "But we all got a little tied up. We all ate way too many walnuts."

As the series star, part of Van Dyke's love of the series was borne out of the wonderful memories he still has of filming.

"It was such a great group to work with," Van Dyke said of his co-stars. "We just looked forward to coming to work every day. There wasn't a star in the bunch — everybody just enjoyed."

More than anything, Van Dyke loved to make people laugh on the set of The Dick Van Dyke Show. With a live audience laughing at him, Van Dyke was unstoppable.

"The shows that do comedy without an audience, I don't understand those people," the actor said. "How do you do it? I need an audience. And we had a great audience every week to play to."
