What short created by Peter Browngardt was greenlit by The Cartoonstitute project?
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: Uncle Grandpa is an American animated television series created by Peter Browngardt. Uncle Grandpa:  It is based on Browngardt's animated short of the same name from "The Cartoonstitute".
