On the Internet, everything is fundamentally both obscure yet ubiquitous, or so it seems. But in real life, there are at least 2 things that seem to be obscure to the point that people don't believe me when I mention it:

1. A Super Nintendo game released in the US as Super Ninja Boy. It was a follow-up to (or maybe remake of) Little Ninja Brothers on the NES. I've even been told that I was confused and that I'm probably thinking of Legend of the Mystical Ninja.

2. On the original Playstation, there used to be a series of demo discs that would have "hidden" features on them if you pressed the right button(s). One of those demo discs had the entire music video for Usher's song "Pony" and other than randos on the internet and my friends/family who saw it with me, I've never met anybody that remembers it. If anybody here does remember that demo disc, I think there was another hidden music video on there, I vaguely remember a band, with various shots of the drummer wearing black athletic-type shorts with a white band around the leg but beyond that I really do not recall.
