Has to be Sheldon.
Sheldon gets the best lines
Sheldon is The Big Bang Theory. The other characters are just filler, with Penny taking the role of sex appeal.
Sheldon is the Core of the show, but I think Howard has gotten a lot funnier these past couple seasons.
that girl I don't know her name but I call her hot girl.
Penny duh.. She want my babies.. Just don't know it yet
