The Best Time Fez Broke Character In That 70's Show

Fans will likely remember the Season 6 episode "I'm Free," when an immigration agent comes to visit Fez and Laurie, Eric Foreman's sister, to see if their marriage is legitimate (this occurs because in a previous episode, Fez and Laurie get married because Fez is at risk of being deported). In "I'm Free," Fez temporarily moves into the Foreman home to convince the immigration officer that the marriage is legit. 

This leads to a funny scene where, when Fez is in the shower, Red Foreman (played by Kurtwood Smith), Laurie's father, opens the shower curtain on his son-in-law. To this, Fez responds, "I don't know what you heard, but this show ain't free!"

Turns out, this scene was just as hilarious to watch as it was to film, because a gag reel shows the actors having to do multiple takes, not being able to control their laughter each time. In the first take, Valderrama can't even deliver his line before laughing. In the second take, he gets halfway through the line before caving in and laughing while closing the curtain, setting up for another take. In the final take, both actors start laughing right after Smith draws back the curtain. At one point, Smith plays a joke and pretends to jump in the shower with Valderrama, before the take ends. Seeing all these takes makes the end result all the more funny.
