Sid and Stinky were such jerks
As an adult whose been rewatching some old episodes lately, I've realized how poorly Sid and Stinky treated their friends.
1) Harold was suppose to be their best friend, yet they tease and mock
Him for being overweight.
2) They also tease Harold for losing to Patty in arm-wrestling and again for hanging out with her.
3) They also tease Patty for her size and looks, I really wish she would've kicked their asses, they would've deserved it.
4) They promise Arnold they wouldn't reveal Iggys secret but do it anyway.
5) Sid accuses Arnold of stealing money.
