As if there were a shortage of black actors in the '90s, Saved by the Bell: The New Class cast Gabrielle Union twice in two different one-off roles: first as Hilary in the season 3 episode, "The Christmas Gift," then as Jennifer in season four's "The Tall and the Short of It." Nobody really noticed that she played two characters on one show, not because it wasn't apparent but because not too many people were watching in the first place. —BG
