Professor Proton from The Big Bang Theory

In The Big Bang Theory, Arthur Jeffries, a.k.a. well-known children’s science TV show host Professor Proton (played by Bob Newhart) is a personal hero of Sheldon Cooper and is hired by Sheldon and Leonard Hofstadter to perform a private science show.  Though typically seen in a tie and lab coat, Professor Proton also has a recurring appearance in Sheldon’s dreams dressed as Obi-Wan Kenobi and offering pertinent life advice.

Amy Farrah Fowler

In Big Bang Theory, Amy Farrah Fowler (Mayim Bialik) is Sheldon Cooper’s friend who is a girl but not his “girlfriend”. She’s rational, blunt, and socially awkward – can’t imagine why Sheldon doesn’t want to date someone who’s basically his female counterpart.

Leonard Hofstadter

In The Big Bang Theory, Leonard Hofstadter (Johnny Galecki) is an experimental physicist and roommates with Sheldon Cooper. He may be a geek, but he’s perfectly normal compared to the rest of the gang.

Raj Koothrappali

In The Big Bang Theory, Raj Koothrappali (Kunal Nayyar) works with Sheldon Cooper and maintains a bromance with Howard Wolowitz. His game suffers from his inability to talk to women sober, as well as his garish sweater vest and jacket combos.

Howard Wolowitz

Despite a highly successful career as an engineer and astronaut, Howard Wolowitz (Simon Helberg) gets mocked constantly by his friends in The Big Bang Theory. He considers himself a ladies man, but that female attention comes mainly from his mother.

Sheldon Cooper

In The Big Bang Theory, Sheldon Cooper (Jim Parsons) has a genius IQ and photographic memory, though he spends most of those brain cycles on comic books, sci-fi, and sci-fi comic books. He himself enjoys costumes, even dressing up as Raggedy C3P-O one Halloween.
