From Homestar Runner Wiki
In the short,
Lookin' at a Thing in a Bag,
Strong Bad,
Strong Mad, and
The Cheat get free drinks. They all want a drink, so they go to
The Field and look at a thing in a bag. They get
Homestar to get drinks from
Bubs' Concession Stand, and he lies about seeing the thing in the bag and
Bubs notices. When there's nothing in the bag,
Homestar Runner says the thing in it is awesome. Even though it is classified as a short, it's actually longer than four of the "full-length" toons.
