The Big Bang Theory Quiz: Can You Find The Odd One Out In This Penny Quiz?

How well do you really know Penny?

The Big Bang Theory first aired back in 2007. It was the first of its kind. Yes, we'd seen many many sitcoms with a group of guys and girls working and dating in America, but what we hadn't seen, was a group of very very intelligent scientists...and Howard.

While a lot of the time some science jokes and references may have gone over our heads, the introduction of a beautiful blonde with about as much knowledge of science as the rest of us, made them less relevant.

We were first introduced to Penny in the very first episode of The Big Bang Theory. She was moving into her new apartment across the hall from Sheldon and Leonard. Leonard instantly fell for Penny, while Sheldon instantly took a disliking to her freeloading and lack of cleanliness.

Appearing in 277 episodes of The Big Bang Theory, there was a lot to learn about Penny over the years. Just how closely were you watching though? Can you correctly identify which of the following answers is the odd one out?
