Hi I don't know if there are any fans of the show here but it's a neat site. This site has 3 rare clamation arnold episodes which came out in the early 90's,Interviews with the creator, and a news story where a girl saves the life of another girl by using the heimlich maneuver that she learned from watching a hey arnold episode. Site also has episode downloads.
If anyone was woring on a set or was planing on making a Hey Arnold dvd set, It would be cool to include those extras. I would make it myself but I don't have the nicktoons channel which I think airs them.
here's the link, let me know what you think.
