From the Homestar Runner Wiki:

Suudsu (pronounced SUD-zoo) is The Cheat’s favorite bedtime snack.

My roommate, in a crazed fit of massive paper writing, decided it would be a good idea to procure some of this amazing liquid. So he, my other roommate, and I walked all the way down to the Bigfoot gas station, it must have been at least 100 ft, to buy some milk and gummy bears. We returned triumphant and my roommate poured himself a glass and added the gummy bears. After a quick drink it was clear the drink needed more bears and the rest of the bag was added.

My roommate decided this was not enough and microwaved his drink. The story is continued with the aid of my digital camera and includes a fantastic short clip of the events.
