I really love all the characters, Red is fucken awesome, he reminds me of my dad but when my older brother's were in high school and all their friends were at our house.

Kelso is funny, sometimes they make him to stupid but most of the time it's hilarious. Eric has his moments and Hyde is probably the coolest guy on the show. Jackie is funny in her own bitch way, she was 14 when she started the show

Fez has to be the funniest though, he cracks me up every time. All the characters are funny though, awesome show.
