‘Big Bang Theory’ Season 10 Spoilers: Episode 11 Sneak Peek Teases Sheldon’s Birthday Surprise For Amy

“Big Bang Theory” Season 10, episode 11 will see Amy Farrah Fowler (Mayim Bialik) celebrating her birthday.

In the sneak peek released by CBS for “The Birthday Synchronicity,” Sheldon (Jim Parsons) decides to wake Amy up at the strike of 12. He greets her by blowing a party favor. Amy isn’t pleased with how her boyfriend woke her up, so she decides to confiscate his toy. Sheldon gives Amy his real gift and explains why he hadn't wrapped up her present. It turns out Sheldon does not like touching scotch tape. Amy opens the gift bag to see a functional image of Sheldon’s brain via a recent MRI.

Amy looks pleased with the gift that she will receive in episode 11, but she’s also anticipating coitus with Sheldon. Unfortunately, the two characters won’t engage in sex this year because everyone’s preoccupied with the arrival of Bernadette’s (Melissa Rauch) and Howard’s (Simon Helberg) baby.

Meanwhile, Raj (Kunal Nayyar) will also spill important information about Bernadette and Howard’s baby just minutes before she gives birth. Since the couple previously decided that they don’t want to know their baby’s gender beforehand, Bernadette and Howard made sure that none of their friends knew as well. However, since Raj has been very involved with Bernadette’s pregnancy, he has known their baby's sex all along.

Just before giving birth, Raj will excitedly reveal the baby’s sex. This will shock Bernadette and Howard and will also make them a bit upset at Raj. But in the end, they forgive him for his mishap and even reward him with a special gift for the time and effort he exerted throughout Bernadette’s pregnancy. By the looks of it, Raj could become the baby’s godfather.

“Big Bang Theory” Season 10, episode 11 will air on CBS on Dec. 15 at 8 p.m. EST.
