'The Big Bang Theory' Season 8 Episode 11 Spoilers: Amy Kisses Sheldon Under The Mistletoe In The Clean Room Infiltration [VIDEOS]

"The Big Bang Theory" Season 8 is returning after a break of two weeks, with an episode titled "The Clean Room Infiltration." This episode 11 will see Amy (Mayim Bialik) throwing a traditional, Victorian Christmas party, while Sheldon (Jim Parsons) will be seeking revenge on her. And, if spoilers are to be believed, Amy is going to kiss Sheldon.

In "The Clean Room Infiltration," a bird enters the clean room at the University while Leonard (Johnny Galecki) and Howard (Simon Helberg) are there performing an experiment. The synopsis of the episode suggests that the two "nearly come to blows" because of that. In the sneak peek of episode 11 of "The Big Bang Theory" Season 8, a pigeon can be seen flying inside the clean room and a shocked Howard is seen asking, "How did the hell a pigeon get in here?" It looks like Leonard thought that Howard must have shut the loading dock doors while the latter was under the impression that Leonard did that. They will be calling Raj (Kunal Nayyar) to help them deal with this work emergency, according to the synopsis.

The second story-line of this episode is Amy deciding to throw an "authentic Victorian Christmas party." Sheldon, who is not fond of Christmas traditions, will be seeking "revenge on Amy for making him celebrate the holidays," according to the synopsis of the episode.

The episode spoilers leaked online reveal that Amy is going to kiss Sheldon in episode 11 of "The Big Bang Theory." Amy and Sheldon will be deciding not to buy presents for each other. However, Sheldon will change his mind and will be looking for a present for Amy to punish her, as she kissed him under the mistletoe while they were shopping for a Christmas tree. This public display of affection is going to make Sheldon angry and he will decide to get his girlfriend a Christmas present and make her feel small. It is Sheldon's way of having the last laugh and ruining Amy's Christmas, as she would not have anything to give him in return. In the preview clip, Sheldon can be seen admitting to Bernadette (Melissa Rauch) that he loves Amy a lot and adding, "Let's find the kind of gift that makes her feel small and worthless."

Sheldon's gift is a photo of himself sitting in Santa's lap. Amy is going to love the gift, according to the spoilers. Amy, too, has something to give to Sheldon, his "favourite cookies from his Meemaw's recipe," the spoilers say.

Also in the episode, Raj's father will be visiting him, minus his mother. In one of the previous episodes, Raj found out that his parents are getting a divorce.
