Mayim Bialik's Accident
On August 15, 2012, around midday (the day after the taping of the first episode), Mayim was involved in an accident when the white Volvo she was driving was hit by a car making a sudden left turn. Mayim's right hand was reported to be seriously injured and not long after rumors were surfacing that she might even lose her fingers. Mayim took to her Twitter (via her husband) that despite being in pain, she will keep all her fingers. She added that her right hand; however, is very impaired, and since she will have a long recovery, her assistant, Brandon, will help her type her blogs. Following that, it was reported that her injury will not disrupt the production of the show, and this fact was confirmed by Bill Prady on his Twitter that Mayim will make it to the next episode rehearsal with "all her ten fingers". Mayim later blogged that she will not be taking any week off from the show. It is now confirmed that, much like Kaley Cuoco's broken leg during the filming of Season 4, her injury will not be written into the show, and will be hidden, as the second episode of season 6 was taped without including her injury as part of the storyline.
