There were two main storylines at the center of The Big Bang Theory Season 8 Episode 18.

And both were hilarious! As if we'd expect anything else from television's top-rated comedy.

First, major friction ensues after a magazine failed to mention Leonard (Johnny Galecki) in an article about the paper he co-wrote with Sheldon (Jim Parsons).

Second on "The Leftover Thermalization," there was blackout at Mrs. Wolowitz's house. In response to this incident, the group gathered around for a final family dinner in her honor.

Sweet stuff. See how it transpired when you follow the prompts on this video and watch The Big Bang Theory online.
