Jan. 8 (UPI) -- Big Bang Theory star Johnny Galecki has said the cast of the long-running sitcom is "comfortable" with it ending at Season 12.
"The only manner in which the cast has discussed wrapping [the show] has been that we're all going to be very sad when that day comes," Galecki said to E! News about when the show might end at the 2018 Television Critics Association Winter Press Tour.
