Character: Penny
Aspiring actress, former Cheesecake Factory waitress and current pharmaceuticals sales rep, Penny started off the series as a stereotypical “dumb blonde” across the hall from the nerdy quartet of scientists. But she’s often the voice of reason and stand-in for the TV audience when it comes to comprehending the show’s scientific world. (We also have never found out Penny’s last name.)

Played By: Kaley Cuoco
Kaley Cuoco is now one of TV’s top-paid actresses, earning $1 million per episode like her co-stars Parsons and Galecki. She’s an avid equestrian and used to be an accomplished tennis player. She and husband Karl Cook share a love of horses, as he’s a professional equestrian and the pair met at a horse show.
