I was just concentrating on Sheldon. He's the tallest one, right? who was drinking the diet coke?
It was interesting the way he answered when the gal came in and said she needed some guinea pigs. He took he literally and then proceeded to tell her where she could find some, and recommended a certain type. It seems like he remembers a lot of "trivial" information, in a very detailed way.
Funny how he never smiles. Very serious.
He seemed T when he was brutally honest.
He seems very J. Well, apparently, he's got OCD - showers twice a day and washes his hands frequently.
I wasn't sure if he was I or E. After he had some alcohol, he became more E.
I think that because he seems to have such a great memory, not just in one or two subjects, I'm going to guess Sheldon is an ISTJ.
