In "Fighting Families", the game show host asks to name seven colors found in a rainbow but there are only seven colors in a rainbow.
How did P.S. 119 increase their score from 20 to 30 if they didn't reach their podium before P.S. 118 did?
If you look closely in the shower scene, Helga's hair is shoulder length, but in Valentines, her her reaches the middle of her back. Her broomstick pigtails from Season 1 and 4 have the same length, but when down, it has different lengths.
When Helga went up to Arnold's window, Arnold saw Phoebe and Helga there. They left, but when they were throwing away the pork rinds, they walked near the trash cans and threw it away. However, if you look back, there were no trash cans there!
When the final question came up, Pookie started singing, but nobody ever rang the buzzer.
Helga bought pork rinds and ate all of them. But, in another episode, she said she hated pork rinds.
Game Show Host: And from PS. 118, meet Arnold and his family. Phil, Pookie, Ernie, and and Mr. Heeee-yun!
Mr. Hyunh: It's H-WIN!!
Ernie: One more comment, Hyunh, and I'll give you a knuckle sandwich, plenty with mustard!
Grandpa: I'll give you both a knuckle sandwich!
Grandma: That's odd, I don't remember packing any sandwiches.
Ernie: Oh, good one, Hyunh!
Mr. Hyunh: You push me!
Ernie: Yeah! Well, Gramps stepped on my toe!
Grandpa: I did not! This is stepping on your toe! (steps on Ernie's foot)
Mr. Hyunh: Pluto, Pluto!
Ernie: Not Pluto, Pluton! You idiot!
Brainy: Huhhh... Huhh... Hi.
Contest Lady: And the winner is Arnold... there seems to be a smudge over the last name.
Stinky: That must be you, Arnold, on the count that you're the only kid named Arnold in this whole danged school.
