Holy crap on a cracker! It's been 14 years since we were first introduced to the gang from The Big Bang Theory.
As played by the incredible Kaley Cuoco, Penny was our entry point into the weird and wonderful world of geekiness and scientific discovery. We learned as she learned! Everything from comic book multiverses to time travel and the theory of relativity were touched upon and in ways much more satisfying than any lesson we had to endure in school. Penny was the every woman who learned smarts from the geniuses that were Leonard, Sheldon, Raj, Howard and later Amy and Bernadette.
Penny appeared in over 279 episodes of The Big Bang Theory across 12 unforgettable series - but how well do you really remember the intricacies of Penny details from those episodes past?
Can you remember the names of Penny's siblings? How about what tattoos she has inked on her body or what tv programs she has seen or not seen. Or even who Penny's favourite Spice Girl was.
