Some viewers of Anthony's televised murder trial were outraged after the Florida woman was acquitted this month of killing her 2-year-old daughter.
Fair Chairman Ron Mossotti said an event management company presented the idea of the dunking booth in which the lookalike sat on a platform labeled "innocent" and fairgoers aimed for a target labeled "guilty."
Mossotti said most people laughed though some found it tasteless and tacky.
