The 'Now Do Classical Gas' meme stems from the 1993 episode of The Simpsons titled 'Last Exit to Springfield.' In the scene, Lisa Simpson plays a soulful blues song on her guitar for a group of striking power plant workers, prompting Lenny Leonard to enthusiastically shout 'Now do Classical Gas!' Lisa then proceeds to play an incredibly complex rendition of Mason Williams' 1968 hit. In internet culture, the phrase is used as a humorous demand for someone to perform a specific, often difficult feat, or as a reference to Lenny’s sudden and specific musical request. It serves as a staple for Simpsons fans and music enthusiasts alike to signal appreciation for virtuosity with a side of workplace comedy.
