I was not very pleased with my Sheldon Cooper. I will most definitely attempt him again (Jim Parsons, if you're reading this - If you come visit me, I'll give you the original of this strip). And I apologise for the poor excuse for The Big Bang Theory set. Backgrounds are just not my specialty.
ps - For those of you who don't watch this show, Sheldon doesn't let anyone sit on that particular seat. He has a brilliant lecture that he gives to anyone who asks why he cannot sit elsewhere. I recommend that you watch it.
