Los Angeles, Jan 8: Actor Johnny Galecki says everybody's very comfortable with "The Big Bang Theory" concluding after 12 seasons. During an appearance at the Television Critics Association winter press tour in Pasadena, California on Saturday, Galecki told reporters that the popular sitcom was most likely going to end in season 12, reports people.com. " "The only manner in which the cast has discussed wrapping ('The Big Bang Theory') has been that we are all going to be very sad when that day comes," said Galecki. "But I think at this point everyone's very comfortable with 12 seasons being a good time to go home and see our families," he added.
