“Hey, Arnold! One of favorites show when I was a teenager. :)“ Wait, how did you watch that show as a teenager? You’re 22, and Hey Arnold! aired from October 7, 1996 to June 8, 2004, so... I don’t know. The first episode is the same age as you, but Hey Arnold! aired for 8 years. I would go through how confusing this coincidence is, but then I’d be here for an eternity.
