House Party - S2-E5
Continuity mistake: Kelly said her youngest brother can burp his whole name Kenneth Leonard Kapowski in one burp. However in the previous year, Kelly had an infant brother named Billy. According to this info, unlikely Kenneth would be younger than Billy.
Suggested correction: Kelly can have more than one brother because in the episode where Kelly gets her job at the Max she said "I cook every night for my 11 siblings". So he could be younger or just have a nickname.
The mistake is valid because she says her "youngest" brother, not "younger." In the episode "The Babysitters" (which was meant to air in season 1 and produced before "House Party"), her brother Billy is an infant and says his first words. Kelly has 6 siblings and she never said she cooked for 11 siblings when getting a job at The Max. She says she sets the dinner table for 9 people three times a night.
Ironically, the show only reveals 5 siblings each in their own individual episode. (#6 is unknown). Bennett (mentioned), Nicki (seen), Kyle (voice heard only), Kenneth (mentioned), Billy (seen) are the 5 of 6 siblings revealed.
Plot hole: When the gang is helping Lisa earn tips at her waitress job, Slater says the more people she waits on the more tips she will make. So they take the food away from the customers before they even get to eat it. How in the world would she make 37 dollars in tips with service like that? Horrible service like that would earn her no tips at all.
Suggested correction: I just watched the episode. The group earned $37 in three hours, and Slater was the one who took food away from customers. We don't see how every member of the group treated every customer. Also, it's unrealistic to say no tips at all." Many people will leave a small tip, at least, for bad service. They may think that a portion of tips are going to other servers or the cooks - I worked at a restaurant like that. They may want to insult a server more by leaving an extremely low tip, i.e. one dollar or less. Maybe they usually like the restaurant, and this is their first bad experience there.
Factual error: It seemed like they had several senior years in the show? They had The Prom year when Kelly, Jesse, were there. Then they had senior year when Tori was on the show when they did the senior Class Rings.
Suggested correction: Actually the first senior year was going to be the end of the show. However they wanted to add another season so they had a second senior year and added the new character.
