10. She wasn’t in the original pilot of The Big Bang Theory
Originally, the character of Penny was supposed to be a much raunchier girl named Katie, so when the original pilot for The Big Bang Theory was shot, a different actress played the lead. Unfortunately for that actress, test audiences didn’t respond positively to the character, so the show switched gears.
Kaley told Vegas Magazine that she actually tested twice for The Big Bang Theory, but it wasn’t until the initial pilot required recasting that she was chosen for the series and the character was renamed Penny.
11. She loves table tennis
Though she gave up playing tennis professionally many years ago, Kaley still loves to hit the ping-pong ball around.
“I bought a ping-pong table for work, one for the house, and [my co-stars and I] play all the time,” she told Men’s Health Magazine. “Guest stars come to our set and ask, ‘Hey, can I play?‘ The rest of us stare at them and think, ‘You do not know what you’re getting yourself into.’ They don’t realize until they start [playing] how so not fun it is to play with us because we get so super-competitive.”
12. She was part of a flash dance mob
Along with the cast and crew of The Big Bang Theory, Kaley stopped in the midst of taping an episode to perform several songs for a very surprised live audience.
