I feel like a freak because I also have a spot. And ever since my parents started watching BBT they call me Sheldon whenever I shoo someone from my spot. In return I started saying "You're sitting in my spot."
Now I'm remembering back to one particular episode, when he bursts up out of the sofa, looking EXACTLY like a zombie, almost giving Leonard a heart attack!! And all over a prank too! (Did you watch that episode?)
sheldon is is from the tbs series the big bang theory sheldon is mostly the very smart guy who loves video games comic books and all sorts of stuff some people don't get what he's saying (sometimes) and some get annoyed or offended on what comments he says to the people on the series.
