Captain N: The Game Master
I was at the Alamo Drafthouse last night and they were showing their weird little videos before the movie starts, and this video came on! I was a little blown away because I used to watch this Nintendo sponsored cartoon all the time, but hadn't thought about it in years.
I laughed and pointed at the screen and said, "Oh my god I used to watch that show, and I totally forgot about that!"
The guy next to us, who I had never met before in my life, turned to me and said, "I was just about to say the same thing! I totally forgot about that!"
For those not in the know, Captain N: The Game Master was a Saturday morning cartoon show that aired from 1989 to 1991. It was about a kid who was sucked into his TV with his dog while playing Nintendo. The kid would run around with a Nintendo light gun, the kind you use in Duck Hunt, and fight bad guys with the help of Nintendo characters like Kid Icarus. The team would surf around on an old school Gameboy for transportation.
I think I loved the show because a) I loved Nintendo, b) the dude's name was Captain N, and c) one of the core values it transmitted was that playing video games might actually save your life on day (if you get sucked into a vortex). In short, it was a brilliant half-hour TV commercial for Nintendo.
There are way more details I didn't remember in the Wikipedia entry for Captain N. There are also a ton of Captain N videos on YouTube. This one is great!
