Just realized something related to both Sam and Freddie... they have traits that Hey Arnold!'s Helga Pataki had. here:
Sam Puckett has Helga's bashing someone (mostly upon Freddie like how Helga does to Arnold or others), tomboy qualities, being forgotten by her parents and having a perfect sibling (Olga=Melanie), while Freddie Benson has Helga's being in love to the main character, the difference is that unlike Helga, Freddie openly shows it to Carly. in short, Sam has 75% of Helga while Freddie has 25% of her, and arguing sometimes with the one who "hates" him (Arnold to Helga= Freddie to Sam)
That was something I found out, could Dan Schneider model both Sam and Freddie by being inspired by Helga?
