It seems the pep talk that Penny gave Sheldon (while tipsy, we might add) also gave her the confidence to go home and "attack" her husband — in a sexy way, of course. When the show flashes forward two months to the gang's trip to Sweden, Penny announces that she's pregnant since Sheldon stars spiraling about all the reasons why she's constantly going to the bathroom on the plane. While we wish we could see Penny and Leonard as parents, this is a pretty sweet way to wrap up their stories, no?
