|Bart and Lisa were invited to Dylan's birthday party, despite the last time when Bart and Dylan spoke to each other was in Toddle Tots. Bart and Lisa couldn't remember what gender Dylan was because Dylan is a boy and a girl's first name. And it didn't help when Marge looked at the invitation and saw a fish theme, because that could have been from a girl or a boy, and secondly when they got to the party and there was a boys area and a girls area. However, Bart didn't take any notice of this matter and started to play a Japanese card game called Battle Ball with other boys.

|Martin's birthday party turned out to be incredibly boring and to cap off the poorly received party, things came to an end when everyone became ill with food poisoning that was caused by serving oysters instead of cake. Springfield Elementary principal Seymour Skinner and teacher Edna Krabappel attended, and during the chaos they went into Martin's pink playhouse, wherein they had a conversation which led to them discovering that they have romantic feelings for each other - and they ended up kissing - in an act witnessed by Bart Simpson (one of the few to escape the poisoning, Lisa did too but feigned sickness so she could leave with an excuse).

|Bart, under the alias of "Bart-Bart", attended the party and saw one of the waiters injure himself repeatedly, and was the only one who could prove that Freddy Quimby didn't attack him.

|Sherri and Terri received a Malibu Stacey wig for their birthday, which Bart stole from them, and impressed the boys by putting on the wig and singing like a girl.

|"Homer Simpson in: "Kidney Trouble""
|While on a trip out, Abe suffered a kidney blowout because Homer would not let him use a toilet.

And so, Bart bought Lisa a laser pointer and Homer bought her a personalized video which portrayed her so bad that she ended up running upstairs in tears, shouting that he doesn't know anything about her.
