The Big Bang Theory could easily be its own Theme for someone to use during their A to Z posting attempt. The four brilliant scientists trying to deal with the normal and average world create tons of laughs with even the most innocuous of pursuits. Sheldon alone is one of the funniest characters in history, more than stupendously played by Jim Parsons.
I won’t hesitate to admit a little writer jealousy at the brilliance in crafting Sheldon’s three knock sequence. While he consistently uses it with everyone, his interaction with Penny (Kaley Cuoco-Sweeting) is the stuff of comedic magic. Penny plays the average blonde with not so much going on upstairs to perfection and is a perfect foil for the ultra-brilliant Dr. Cooper.
