Cast member Kaley Cuoco arrived at "An Evening with The Big Bang Theory" at the Academy of Television Arts and Sciences in Los Angeles yesterday channeling an ancient Japanese warrior with her top-knot hairdo. Um, we`re not crazy about the look. What do you think? See more photos after the jump. Kaley admits she almost killed co-star Johnny Galecki in a scooter accident, and now show producers don`t trust her when she gets in the driver`s seat. She told Maxim, "I was driving a Vespa in the Dominican Republic with my cast mate Johnny Galecki on the back like a little b**ch. I ran us right into the wall, and he went flying. I almost killed Johnny Galecki. I`m dead serous."
