The nerds make a big deal out of the scientifical inaccuracy of Superman catching the falling Lois Lane who is falling from a skyscraper
Sheldon points out that she would have been cut into 3 pieces while superman catches her with his iron arms 2 feet above the ground
In fact: He catches her not even half way to the ground with a charming smile and also has time for the helicopter
I really like BBT (on my 3rd run), still it often insults movies or claims to know more than it actually does
so get your facts straight for the last 4 episodes!
