Did you know that rebellious Bart Simpson, the eternal 10-year-old, is actually voiced by a woman? Nancy Cartwright, born on this day in 1957, has been playing the foul-mouthed kid since The Simpsons premiered more than 20 years ago as a segment on The Tracy Ullman Show. Cartwright isn’t a one-trick pony, though – she is also the woman behind other characters such as Ralph, Nelson, and Todd Flanders – and she owns her own production company. What makes her so goofy and likable? Perhaps it is due to her multiple placements in gregarious Sagittarius – Moon, Venus, and Saturn, to be exact.
