I have looked and looked for the thread regarding this question, but I cannot find it. Earlier there was a question about the character Fez and what his real name was.
I was watching the 100th episode musical celebration (hilarious, by the way) and it was explained that Fez is not the character’s real name. The one time on the show he said his name was in the hallway of a school and a bell was ringing as he spoke. Even reading his lips wouldn’t do any good, since he was reciting the names of the other actors. The country he comes from is also intentionally a mystery- sort of like the Springfield joke in The Simpsons.
As for the 100th episode-
Just about everyone seemed to sing on their own, but I am 99% sure Mila Kunis (Jackie) was lip synching.
What did you guys think of the episode?
And what the heck happened to Eric’s older sister?
