What short created by Peter Browngardt was greenlit by The Cartoonstitute project?
The Cartoonstitute: The Cartoonstitute was a planned Cartoon Network project created by Cartoon Network's executive Rob Sorcher that would have been a showcase for animated shorts created without the interference of network executives and focus testing. The Cartoonstitute:  Of the shorts which were made, only "Regular Show" and "Uncle Grandpa" have been greenlit to become animated series (the latter was initially greenlit as "Secret Mountain Fort Awesome", before becoming a series of its own). Uncle Grandpa:  It is based on Browngardt's animated short of the same name from "The Cartoonstitute".
