Who Are You - S6-E15
Factual error: In this episode, when Donna and Jackie are arguing about who is going to go outside, Jackie is seen holding a box of Chips Ahoy cookies. The logo seen on the box was used in the late 90s and early 2000s, rather that the logo used in the 1970s. (00:17:30)
Visible crew/equipment: In the scene in Bargain Bob's where Donna is talking to Bob, the end of the set and lights can be seen in the reflection of metal cookware that Bob is tying balloons to. (00:07:50)
Kitty Forman: Oh good God, you kids switch partners more than square dancers!
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.
Answer: It's Ashton Kutcher's dog.
