by at .  Updated at . Comments

Sheldon's life with never be the same after he showed up to surprise his mother in Texas on The Big Bang Theory Season 7 Episode 18.

As Sheldon approached the door, he looked in the window and saw his mother having sex. Sheldon didn't know how to handle that information, but Howard convinced him to visit her. Sheldon's response was hilarious and provided some of the funniest lines ever.

While they were in Texas, Raj set up a surprise Murder Mystery dinner for his friends. They weren't nearly as enthusiastic about it as he was. It led to honest reveals and conflict between the friends.
