Big Bang Theory–As Sheldon said in the episode, “Need I remind you that not a lot of scientific discoveries were made by people having a good time?” He was out with Penny, Bernadette and Amy on their girls night as a result of lawyer Priya managing to outsmart him on various parts of the Roommate Agreement. The girls wanted to take him dancing, which he’s quite good at, given his Southern upbringing, filled with forced dance lessons and a cotillion. They also asked him a question viewers were probably wondering about, whether or not Sheldon’s ever kissed a girl. As it turns out, he once gave mouth to mouth to an elderly nun, and she still sends a Christmas card, but that’s it. After Sheldon and Amy’s cha cha (no, really), he takes her back to her apartment, where she resides with a smoking monkey, who is part of her department’s nicotine addiction study. Emboldened by liquor, Amy kisses Sheldon. Like, a Saved by the Bell kiss, but lips on lips regardless, and Sheldon liked it! In the end, Sheldon also outsmarted Leonard and Priya, by drawing up a new agreement and forcing Leonard to sign it, or else he’ll skype Priya’s parents and blow the lid on their relationship. “You may have gone to Cambridge, but I’m an honorary graduate of Starfleet Academy!”
