The quirky showtune De Lovely, frequently called "It's De-Lovely", was sung by Ethel Merman, Scooter, and Gonzo as part of a musical medley in episode 122 of The Muppet Show.

The song was originally introduced on Broadway by Ethel Merman and Bob Hope, in the musical Red Hot & Blue (in 1936). It was subsequently interpolated into revivals of Anything Goes. In Episode 4305, Cookie Monster says, "Celery delightful! Celery de-lovely! Celery delicious!"
