Kaley Cuoco Reveals the Whole 'Big Bang Theory' Cast Is Sick -- See the Pic!

By
Oof, looks like the cast of The Big Bang Theory could use a day off.
Kaley Cuoco posted a snap to Instagram on Tuesday of her and co-stars Mayim Bialik and Jim Parsons all wearing sick masks on-set.
"When everyone at work is sick," the 30-year-old actress captioned the photo. "#powerthrough."

OMG, go home, everyone!
Hopefully the cast won’t be passing their germs along to Taxi star Judd Hirsch, who has been tapped to play Leonard’s dad in an upcoming episode.
"There's so many family members that we haven't met yet," executive producer Steve Molaro told ET ahead of last week's PaleyFest. "Penny's Mom, Leonard's dad, Penny's brother -- which is a great one that I'm interested in -- Sheldon's brother, and Howard's dad is floating around out there."
