It's not often that I get choked up watching The Big Bang Theory.
But this week, The Big Bang Theory Season 8 Episode 18 is an episode that brings on tears. "The Leftover Thermalization" not only pays tribute to the character of Mrs. Wolowitz, but also to the actress who played her – Carol Ann Susi.
Don't get me wrong, there's no room for ugly crying here. It is still a comedy, after all. The way the tribute is done is the perfect balance. It still allows the characters to be themselves, and it still leaves room for plenty of laughs.
