Marshmonica as Endorsed by John Popper

Dateline, 2058: In an effort to feed as well as entertain the homeless, George and Neal invented the first edible harmonica. Much to George's dismay, the harmonica, comprised of marshmallows, candy canes, and prunes (monikered "Marshmonica") was criticized as the world's worst food - both in taste and in nutrition, but got rave reviews by harmonica virtuoso John Popper who purchased them in bulk. George's later edible instruments, including the hamburchordian, cheeseborine, Jaguanstophone, and pizziano were even less successful. Although the Tubagna, a combo tuba/lasagna creation, was in the works, and showed great promise, George and Neal abandoned the project altogether, when the homeless actually banded together and offered to pay them to stop.
