Kaley Cuoco was on The Late Show and she told David Letterman that she is having the problem of falling asleep on the set of The Big Bang Theory all the time.

After seeing how out like a light she is, she never better work with Quintin Tarantino or he will introduce her to Big Gerry. Oh wait maybe she should work with him…
