That '70s Wiki

"Eric's Birthday" is the second episode in the first season of That '70s Show, and second episode overall. It aired on August 30, 1998.


Red convinces Kitty to leave Eric alone during his surprise birthday party; Eric's older sister arrives.


Eric’s 17th birthday is coming up and he does not want a party because he feels that he is to old for birthday parties. Unfortunately, Kitty is planning a surprise party against his wishes. She also has invited his older sister Laurie home from college for the event. Eric, knowing that the only reason that Laurie is home is for Eric's "surprise birthday", asks Laurie to help convince his mother to call off the party.

During these events Kelso tries to attract the attention of Eric's older sister even though he is in a relationship with Jackie. Donna is also stressing over what she should get Eric for his birthday because she is unsure of the state of her relationship with Eric, having kissed him after the Todd Rundgren concert.

    • In the episode Magic Bus, Eric had his birthday and it was explicitly and more recurrently mentioned that he was turning 18.

    • A similar situation would happen in the episode Eric's Burger Job, where Donna had a younger sister named Tina Pinciotti, who would also be denied in future episodes.
