Where'd the Cheese Go? by Ween is a funny little song that has a story attached to it.
In 2002, the advertising agency for Pizza Hut approached Aaron Freeman and Mickey Melchiondo, the duo who make up Ween, to record a promotional jingle, which resulted in a 30-second recording of "Where'd the Cheese Go?". It epitomized Ween-style irreverence but did not appeal to the agency, and Pizza Hut rejected several versions of the song outright. True to form (and somewhat indignant), Ween rerecorded the same song with new lyrics as "Where'd the Motherfuckin' Cheese Go At?"
