Butterfinger BB's
Marble-sized spheres of Butterfinger — crispy peanut-butter core wrapped in chocolate — sold in resealable pouches and at movie-theater counters. The Simpsons were the face: Homer eternally scheming to get at Bart's stash, Bart warning that nobody better lay a finger on his Butterfinger. Launched in 1992, discontinued in 2006 with no explanation — and fans never stopped asking for a comeback.
