Miscellaneous

J.G. Quintel also created two shorts while in college with characters that resemble the present cast.

Title	Date	Description
2 in the AM PM (Censored)	2006	Two gas station workers have to work at two-o-clock in the morning during Halloween. When the two eat a chocolate bar, the chocolate was filled with LSD by one of the clerks (he accidentally said he put marijuana on the candy first) which caused them to get intoxicated and transform into different characters such as a blue jay and a gumball machine (which were the models of Mordecai and Benson respectively). When a police officer is about to enter the store, they had to concentrate to turn back to normal. They turned back but the policeman turned out to be a super alien. This short never aired on television, presumably due to its crude animation and adult content.
"The Naive Man from Lolliland"	2005	The ambassador of Lolliland visits the United States for the first time (now called Pops in Regular Show). When eating at a restaurant, when he had to pay for the food, he paid with his currency; lollipops. His payment caused many conflicts with the chefs and workers in the restaurant. This is the first appearance of the prototype Pops and his driver is named Benson which would later be the name of another character in the series. Like Adventure Time, this short aired on Nickelodeon.

The following is a theatrical short and can be found in some showings of Rio (others have Scrat's Continental Crack-up instead), African Cats or other PG or G movies. Itself has been featured on the AMC First Look Play block before African Cats showings in AMC Theatres. It can also be seen on the Cartoon Network website, where a ringtone from the short can be downloaded.

Title	Date	Description
"Mordecai and Rigby: Ringtoneers"	2011	Mordecai and Rigby try to write a hit song. When their coworkers doubt it, the duo try to prove themselves by showing their song to a record company (Really Cool Records). When that fails, Mordecai and Rigby propose a variant of their song as an idea for a ringtone (though they keep it to themselves).
