Summary
Lizzie and Miranda are ecstatic about being invited to a pool party given by their heartthrob, Danny Kessler. Mrs. McGuire is excited for Lizzie too until she finds out it's on the same day as grandma's 80th birthday party. She tells Lizzie she has to go to her grandma's instead and Lizzie is furious. The next day at school Miranda temporarily gets on the good side of Kate, the girls' former best friend who has literally and figuratively outgrown them. Kate invites Miranda to hang out with her crowd, causing a conflict between Miranda and Lizzie. At home Lizzie catches her mom on the phone making up a lie to get out of a commitment and accuses her of being a hypocrite. Gordo helps Lizzie to smooth over her differences with Miranda. Mom tells Lizzie she can go to the party after all, but she decides not to and spends the day with Gordo.

Bloopers
- After Danny Kessler invites Lizzie and Miranda to his pool party, Miranda looks directly at the camera, this shouldn't have made it to the final cut.
- When Lizzie is thinking to herself "It's okay. It's okay. I don't need my mother. I don't need my best friend," the book open next to her is The Golden Book encyclopedia, Volume III - Boats to Cereals. Pictured are Lewis Carroll, George Washington Carver, and the Caspian Sea. When Lizzie says "I don't need anybody," the same book is open to an earlier page. It shows the illustrations from the article about candy.
- When Kate walks toward Miranda in the school hallway, the shoulder strap on her bag is in across her chest, in the next shot it is beside her chest and in the following shots it's once again across her chest.
- The calendar hanging on the refrigerator is turned to the month of May instead of one of the fall months. This seems odd since the early episodes make it appear that the first season begins with the start of the school year.
- Lizzie is shown in a camera shot from the inside of her locker, where she takes off a bracelet and hangs it up. In the next shot from a camera angle outside the locker, the pictures and other contents of the locker are different. Then when the camera goes back to the inside shot, the bracelet is no longer hanging there.
- In this episode, the girls' gym uniforms are grey, but in others they are blue.
- Lizzie says she'll feed Matt's book to his gerbils, but there is never any mention of gerbils or any pet after that.
