Reality TV's Most Shocking Moments:
Jessica Doesn't Know What Tuna Is
It's perhaps the moment that catapulted Jessica Simpson from a second rate Britney Spears/Christina Aguilera to a star in her own right. During an episode of her and ex-husband Nick Lachey's MTV reality show Newlyweds, Jessica mistook a can of tuna for chicken because of its name -- "Chicken of the Sea." The look on Lachey's face when his new bride asks the infamous question, "Is this chicken, what I have, or is this fish? I know it's tuna, but it says 'Chicken by the Sea,'" is priceless and perhaps a sign of their divorce to come.
