"One Beer" is a song recorded by American hip hop duo Madvillain, originally intended for inclusion on their debut studio album Madvillainy.

[7] The Japanese anime-styled video features multiple characters as Cyclopes fighting over the last can of beer, including DOOM himself and Madlib's alter ego Lord Quas.

[8] In the video, a young Cyclops girl drinks from a can of beer, and later takes a psychedelic mushroom dropped by Lord Quas, sending her into a drug-induced hallucination where she believes she is shrunken down and chased by a three-eyed cat.

"One Beer" was originally recorded over the beat used by Madlib and J Dilla for the song "No Games" on the Jaylib album Champion Sound.

[14] The only copy of this remix, dubbed the "Drunk Version" by label Stones Throw, was burned to a CD and then lost in Madlib's studio.
