Sheldon Cooper

Sheldon Cooper is one of the main characters of the TV-show The Big Bang Theory. He is extremely intelligent, but due to what appears to be Asperger's Syndrome, he is incapable of understanding other people and sarcasm. That said, he is probably the most hilarious character on TV right now. Although he would probalby look upon the tomfoolery of the show with haughty derision.

Leonard: How was Nebraska?
Penny: Oh, better than North Dakota.
pause
Penny: Guess that joke's only funny in Nebraska.
Sheldon Cooper: With the data at hand, you really can't draw that conclusion. All you can say with absolute certainty is that joke is not funny here.

Shelden

Shelden is a wonderful person. He or she is either very determined in life and will make something out of it. Shelden is very cool, funny, and very brave. But he is sometimes shy with the person he likes, and sometimes uncertain of who he likes. He does things out of people's expectation. He makes everyone fall for him with just eye contact and smooth talking. Other then that Shelden is just amazing.

Person 1 : "Why are the girls giggling over there?"

Person 2 : " Probably talking about a Shelden."
