The cast of 'The Big Bang Theory' dishes on the adulation they received at this year's Comic-Con, and the possibility of a kiss between Sheldon and new girlfriend Amy on 'The Early Show' (weekdays, 7AM ET on CBS).

Simon Helberg, who plays Wolowitz, said one over-enthusiastic fan at Comic-Con actually pulled his hair, but he enjoyed the attention nevertheless. "I was kind of giddy and I pretended that I was really offended. I told my wife, 'Craziness out there! It's so annoying. This girl pulled my hair. I need to lay down for a while,'" he said.

Jim Parsons and Mayim Bialik, who play the show's new power couple of Sheldon and Amy, speculated on the possibility of a kiss between the two, but had a hard time even coming to terms with the concept.

"I literally can't fathom, and it's nothing against you," Parsons said, turning to Bialik.
