"The Skywalker Incursion" is the nineteenth episode of the eighth season of the American sitcom The Big Bang Theory. The episode aired on Thursday, April 2, 2015. Sheldon and Leonard go to Skywalker Ranch to try and get in while the others are cleaning out Howard's garage for a garage sale. A battle of table tennis ensues over Howard's Doctor Who TARDIS machine. Sheldon is working on the opening joke for their lecture on Leonard's theory at UC, Berkeley."What do you say to a graduate of the UC, Berkeley physics department? I'll have fries with that." Penny quips that when they chase them, Leonard will have to run faster than Sheldon. Sheldon also has a PRK or Public Restroom Kit stocked with everything he needs including toilet paper and a mirror to check under the stalls for weirdos. How weird is that? Sheldon and Leonard are on their way to give a lecture at UC Berkeley and have plenty of time. Sheldon plays a game of "I can't spy" which includes sub-atomic particles. Leonard guesses the type of subatomic particle and the number of them right away so Sheldon does want to play anymore.
They both think it's cool to be on a road trip and presenting a paper at another university together. Sheldon is so happy he's going to let Leonard turn on the radio and listen to music. He tells him to " Play that funky music white boy", but never heard of the song his reference came from. At 's house, the rest of the gang is preparing for a from the items in the . is in charge of since she has been going to garage sales forever. finds a table which Howard used to play with his . Raj and Penny used to play, while Amy only served since she had no one to play with. Howard is upset that is planning on selling his . He wants to save it until it's worth half what he paid for it. Bernadette doesn't want it moved into the . Listening to the radio Sheldon hears the "Play your funky music, white boy," Sheldon is confused that because they are asking the white boys to play it and yet the white boys are listening to this funky music. It's a paradox so Sheldon turns it off since music should be fun and not contradictory.
Due to being ahead of schedule, they decide to head to Star Wars director George Lucas' headquarters at Skywalker Ranch and see if they can get in. Sheldon gets "so excite, that he just can't hide it", though he again misses his reference to a popular song. Penny and Raj are playing ping-pong, though not too competitively. Bernadette wants to update the house to tasteful modern instead of Jewish mother ketchy. Amy talks about pricing the TARDIS, while Howard still wants to keep it. Bernadette suggests that they arm wrestle for it. Bernadette doesn't thinks that's fair since he grew up with it, though he just used it as a Transformer-Thunder-cats battlefield. Penny offers to play for Bernie because of all of the Doctor Who episodes Leonard has made her sit through. Howard chooses Raj since he was a champion boy's school badminton player. The fate of the TARDIS will decided by a Game of Thrones battle on the battlefield of Transformers and Thunder-cats. Leonard drives up to the Skywalker Ranch and are in awe of it though it is so plain.
Sheldon wants to try and get in. Leonard uses the and tells the that they are big fans, but not the crazy type that have a filled with and rope. The guard can't hear them and buzzes them in. Next they reach the security guard and Sheldon says they have defeated the first quest. Leonard insists that they are trying to meet George Lucas, not slay a dragon. Leonard just wants to be honest with the guard. As a back-up plan Sheldon hopes that they have a nurse's office which will work as long as Leonard has a willingness to be gently stabbed. Leonard tells the guard that they don't have an appointment, but they're really scientists and big fans. The security guard won't let them in. Sheldon claims that he does the voice-over for Yoda. The security guard says no, but offers them free hats and t-shirts as souvenirs. Sheldon jumps out of the car and runs in. Other guards chase him and he gets tased in front of Leonard. Penny is playing Raj and is losing 8 to 4. Bernadette tells Raj if he wins the TARDIS can be moved to his apartment.
It would look great as his front door since the TARDIS is "bigger on the inside". Raj decides to lose. Howard demands a new champion and wants Amy to play for him. She claims to be rusty, but has a fast powerful serve that throws Penny. Bernadette chooses Raj to replace Penny. Sheldon and Leonard are now being held in a detention room with another guy. Sheldon wonders if they are going to call the . Leonard sarcastically says that officers will probably take them to a in the . Sheldon asks the other guy what he was in for. He wanted to get in and say to George Lucas for creating a where he fit in. He also tried to with a . Sheldon joins Leonard and tells him not about the other guy, rather about the statue garden they have. The guard lets them go with a , but they are not to return or they will be . Also, they will have their taken for posting in the guard . The Wookie-kissing guy wants to know if he will get the same treatment. But the guard will not let him off so lightly. Sheldon wants to know if he can have his picture taken with George Lucas.
After getting a dubious look from the guard, Sheldon says in his best Yoda voice impression, "Quite grumpy, you are." The match is to eleven points. Raj can't return Amy's power serve and Amy can't return Raj's serves. The game goes to 10-10. Final point would allow Howard to keep his TARDIS until Bernadette convinces Amy that if she loses, she can have the TARDIS, replace her bedroom door with the box's door and lure Sheldon into her bed. So Amy throws the game and Howard loses. The door is installed as Amy's bedroom door. Bernadette tells her that if the TARDIS doesn't get Sheldon into her bedroom, then nothing will. Leonard is climbing the stairs mad at Sheldon because they almost got arrested and missed their chance to give their lecture. And they were held in a room with a Wookiee crazy sex fiend. Sheldon's upside is that they got onto Skywalker Ranch which no one they know has done and with all the times he has irritated Leonard, he got to him him hit with a taser. Leonard does admit that they could call it an adventure though Sheldon still hasn't recovered his sense of smell since his tasing.
