• The show's creator, Chuck Lorre, based the characters on his friend, a brilliant but socially awkward computer programmer who struggled with anxiety.
• Sheldon's obsessive tendencies and Raj's difficulty interacting with women were both drawn directly from the experiences of Lorre's tech-savvy pal, giving the sitcom an authentic, insider feel.
