This cache used to be one of eight caches in a series based on the American television sitcom The Big Bang Theory (BBT). It is now a stand-alone multi-cache.
You don't need to be a fan of The Big Bang Theory to find this cache; however, you may enjoy it more if you have some knowledge of the characters and premise of the show.
This is a simple, two-stage multicache. It IS Penny's, afterall.
