10 Years Later: 'That '70s Show' Secrets Revealed

— -- It’s hard to believe the hit comedy series "That '70s Show" stopped production 10 years ago, especially when you consider how many loyal fans the gang of high school students still has.

Wilmer Valderrama, who plays the beloved foreign exchange student Fez, sat down with ABC News at Sharps Barber and Shop, where he partnered up with Old Spice to help guys 'Right Their Hair Wrongs,' and talked pre-shoot rituals, secrets of the set and what the cast is up to now.

Before filming every episode in front of the live audience, Valderrama said the cast would gather backstage. Like a team, they would put their hands in the middle of the circle and decide on a word to represent the episode and break.

“The word from season 1 to season 8 became more and more ridiculous,” Valderrama said with a laugh, remembering when "dumba--" was the mantra of choice. “It was this stupid, stupid stuff but we would basically come up with all these crazy things and have this funny moment together.”

Another little-known fact Valderrama revealed was his character’s real name, an unanswered mystery for the show’s audience. In one episode, when Fez was asked his real name, the sound of the school bell ringing blocked his response out completely.

But Valderrama decided himself that Fez’s real name was in fact the first name of each actor on the show. “I said that is what Fez’s real name is, because that is what he is,” he explained. “He is a little bit of all the characters on ‘That '70s Show.’”

Most heartwarming of all, Valderrama said the cast still gets together at least once a month for dinner at a costar’s house.
