Continuity mistake: In the scene where Donna, Kelso, Eric, and Hyde are in The Hub after Eric Gets Suspended, Donna gets mad at the guys and leaves. But two shots later when Hyde is seen smiling and sipping his soda, you can see Donna's hair on the left side of the shot as if she was still sitting where she was before. (00:03:00)

1 mistake in Eric Gets Suspended
Starring: Mila Kunis, Ashton Kutcher, Topher Grace, Danny Masterson, Laura Prepon, Wilmer Valderrama
Fez: Having sex with someone you work with is horrible. I don't know how Donny and Marie do it.
Trivia: In the fifth episode of the first season, Donna is left alone to babysit her little sister Tina. Both Tina and Valerie, Donna's older sister, were written off the show, much the same way as Richie's older brother Chuck, on Happy Days, or Laura's younger sister Judy, on Family Matters.
