That show was ok back in the days.
But...I have one question that puzzles by this day.
I think its the ep's where Arnold's grampa tells him the story about his mom and dad. He was reading in thier journal. Around the end of the eps, where Arnold was looking through the journal, outside, at the very end of the page there were to pages was stick together. Arnold open it and found a map and runs back inside to tell his grampa.
All I want to know...WHAT HAPPEN AFTER THAT?!?
Its one of the biggest cliffhangers I ever seen.
