Carnegie Hall is a famed concert hall in Manhattan, regarded as one of the most prestigious locations in the world for both classical music and popular music.

• In Sesame Street: 20 and Still Counting, Kermit asks passerby Don Music how to get to Sesame Street, to which Don replies "Practice!" Kermit corrects him saying "that's how you get to Carnegie Hall!"

• In the direct to video special What's the Name of That Song?, the Two-Headed Monster gives a tourist directions to The Statue of Liberty, Tribeca, and Carnegie Hall ("Practice, Practice, Practice!").

• In the Pepe's Profiles interview with Fozzie Bear, Fozzie mentions he'd like to play Carnegie Hall one day. Pepe the King Prawn sets him up for the standard joke, but Fozzie instead fumbles over the actual directions.
