3. The real mind behind the "Big Bang Theory" flash mob was Kaley Cuoco's sister, Briana.
Last October, Kaley Cuoco led the cast and crew in a giant flash mob set to Carly Rae Jepsen's "Call Me Maybe." Cuoco's sister, Brianna choreographed the entire thing.
As a result, Briana landed a cameo spot on the Valentine's Day episode of "Big Bang Theory." She also choreographed another big scene on co-creator Chuck Lorre's other show, "Two and a Half Men."
