Longtime fans of "Spongebob SquarePants" will surely remember King Neptune's debut in Season 1, Episode 19 ("Fools in April/Neptune's Spatula"). In this episode, SpongeBob proves he is worthy of wielding King Neptune's Golden Spatula. In the years since, the character has made several additional appearances, with big parts in four episodes of the series and a major role in 2004's "The SpongeBob SquarePants Movie."

Although Jeffrey Tambor portrays the character in the franchise's first feature film, actor John O'Hurley lends his voice to the role in the television series. O'Hurley's run as King Neptune is certainly memorable, but the star's most notable role throughout his illustrious career is, without a doubt, eccentric clothing catalog magnate J. Peterman on "Seinfeld." He is also known for hosting the "Purina's Annual National Dog Show" and for his championship run on ABC's "Dancing With the Stars." But after having such a rewarding run, what keeps John O'Hurley coming back for more?

In an interview posted on David Morris' YouTube channel, John O'Hurley discussed acting after Seinfeld and how he chooses each role he takes. He said, "I live literally by my imagination. Whatever my imagination tells me to do, those little pictures in my mind, the daydreams that I have, I always follow that because I always believe that's what I am supposed to be doing. That I'm being led in the direction, so I don't listen to my mind. I listen to my imagination, and it's never steered me wrong."
