At one point when this short was uploaded to YouTube.com it became viral to the point of having 2 million views.
The old man who appears near the end was once going to be in an episode called "Diamond Jim" of the full series but that episode was scrapped.
While the original pilot for the short has been released, Pen was asking Nickelodeon to have his full show to be aired on their channel, but they rejected it twice because they didn't care about how he was doing. Years later, Cartoon Network ended up picking this show up and becomes a massive success on television industry.
