Regular Show is an animated show created by J.G. Quintel. Its first episode aired on Cartoon Network on September 6th 2010, but before that an 11 minute pilot was aired called "First Day". Before even that, however, two other pilots were made, one of them being Flash animated. The story of this pilot is not known, but it's likely similar to the final pilot.
The full Flash pilot hasn't been put online as of yet. However, some clips of it are available.
