For a lot of people, The Big Bang Theory is their favourite thing in the world. They wear 'Bazinga!' t-shirts, quote the show and, to be fair, it's probably quadrupled the sales of comic books. So fair enough.
Plus, it's probably giving Star Trek a whole new host of fans and I'm okay with that.
You (like me) may not be the show's biggest fan, but it's certainly made household names out of the main cast.
One of those stars is Kaley Cuoco. However, she very nearly didn't get the role of Penny which propelled her into A-lister stardom.
Before you say it, yes, I know she was on 8 Simple Rules. But hardly anyone watched that.
There's some proper interesting stuff about Kaley that you may or may not know, so let's delve in.
She wasn't originally supposed to play Penny.
So the main female was originally going to be played by a Canadian actress by the name of Amanda Walsh. You may have seen her in Disturbia, Ghosts of Girlfriends Past or even Beauty and the Briefcase. No? Well, anyway, in the pilot episode, Amanda's character was called Katie. Sadly, CBS rejected the show and that was that.
Amanda is the one on the left...
After a bit of re-jigging, Kaley replaced Amanda and her character was renamed 'Penny'.
And that, my friends, is history.
She played 'little Ellen' in Ellen Degeneres' show Ellen.
So yeah, you must know Ellen Degeneres? If you don't, she's the one who does the voice of Dory in Finding Nemo and Finding Dory.
Well anyway, when Kaley was younger she actually played the little version of Ellen. So it's kind of like Little Ant or Little Dec ended up being A list celebrities.
That would be weird.

She was a nationally ranked amateur tennis player.
She has also played tennis since she was three years old. In fact, she was a nationally ranked amateur tennis player before acting full-time.
She's done a lot of voiceover work.
Like Ellen, Kaley has also done loads of voice-over work, and was actually the voice of one of those big-headed dolls, Bratz, when they had their own TV show. The things you do to make it in showbiz, ay?!
So there you go. Kaley's done loads of stuff and doesn't just work in a cheesecake factory restaurant or whatever. Happy birthday, Kaley.
