Our whole universe was in a hot, dense state, then nearly fourteen billion years ago expansion started, wait. The earth began to cool, the autotrophs began to drool. Neanderthals developed tools. We built a wall, we built the pyramids. Math, science, history, unraveling the mysteries. That all started with the big bang!

This theory is for scientists like Sheldon and Leonard to argue about. Meanwhile we, the ordinary folk, can talk about when and how the friendship between two leading characters of the legendary show, The Big Bang Theory started.

When the pilot of the show aired on September 24, 2007, no one imagined that clean freak Sheldon and messy Penny would become Shenny.

The weird, but strong brother-sister relationship between these two brought into existence many epic moments and sarcastic dialogues. Always fighting, mocking each other, but having each other's back while in trouble. Penny even helped Sheldon solve string theory. Who would have thought?

It's time to see how well you remember Shenny's friendship. Even Sheldon will fail the last questions of this quiz. Bazinga! He won't.
