Guesting on Big Bang has become something of a rite of passage.
So how will the gang meet Nathan? Simple: they see him at a restaurant and debate whether or not to ask him for a photo!
Clearly, their geekiness gets the better of them! To see how well it works out, you can watch Nathan's episode February 19th on CBS!
