It's one of the most popular sitcoms on television these days, so it's no surprise that the cast of CBS' "Big Bang Theory" is demanding a raise.

According to Deadline.com, Mayim Bialik and Melissa Rauch went up from $20,000-$30,000 per episode and "$60,000 this upcoming episode, with their pay steadily increasing every year to reach close to $100,000 an episode by the end of their contracts."

Johnny Galecki, Jim Parson, and Kaley Cuoco are currently earning $325,000 per episode and are projected to earn up to $500,000 per episode.

Meanwhile, the cast is getting ready for the 65th Annual Emmy Awards on Sunday (September 22nd). The comedy is up for eight awards.
