I am home for a week, and as a result have been forced to watch The Big Bang Theory with my sister, who watches it incessantly. It is quite funny, but what I enjoyed most so far was Christine Baranski as Leonard's mother, because she is fabulous and because it is fun to imagine her as Diane's twin sister. She would, no doubt, ask Diane if she has consummated her relationship with her much-younger male colleague/partner every time they met and pester her to get a brain scan, because it's crucial for her understanding of her own brain.
