Locked Out is the 13th episode of Uncle Grandpa season 1, and the 13th overall episode of the series.
Uncle Grandpa and Belly Bag get locked out of the RV and must get back so they Mr. Gus, Pizza Steve, and Giant Realistic Flying Tiger, can go on their mystery dates.
The episode starts off with Uncle Grandpa greeting everyone in The UG RV and then asking them what they were going to be doing that day. Pizza Steve reminds them that they have mystery dates set up tonight. Mr. Gus worries about who will watch the RV while they are gone, but Uncle Grandpa reassures him that he has a security system put in place. Mr. Gus and Pizza Steve point out that it is outdated. So Uncle Grandpa updates it and reassures them that everything will be okay.
Immediately after they update the security system, the RV crashes into a telephone pole. Uncle Grandpa excitedly announces that it is time for him to help a kid, because every time the RV crashes he helps a kid. Later that night when Uncle Grandpa comes back to the RV, he finds that he accidentally locked himself out of the RV. He tries to get his friend's attention by knocking on the door and looking into the windows, but that does not work. He decides the best course of action would be the knock the door down. He gives the door a dramatic super punch, which ended up setting off the alarm.
Meanwhile inside the RV, Pizza Steve freaks out about the alarm going off and believes someone is trying to break in. Pizza Steve makes Mr. Gus his body guard as the travel outside of the RV to check out what caused the alarm to go off. They step out, walking out into the grass until they see a rustle in the bushes. Pizza Steve becomes frightened, but quickly calms down when he finds out it was just Uncle Grandpa. Uncle Grandpa begins to explain to them how he got locked out and has been trying to get their attention, but he accidentally locks himself in the RV while giving them the demonstration.
Mr. Gus and Pizza Steve try to think of what they should do next. While inside, Uncle Grandpa accidentally sets the RV to self destruct mode while trying to shut it off. They end up coming to the conclusion that they need to summon Uncle Grandpa to help them, despite him being locked inside the RV. Mr. Gus attempts to call Uncle Grandpa, but fails. Pizza Steve does the correct Uncle Grandpa call, and another Uncle Grandpa comes to their aid.
The Uncle Grandpa inside the RV explains to the Uncle Grandpa outside the RV what happened, in which the Uncle Grandpa outside of the RV states that they simply must disarm the security system by destroying all of its arms. The UG RV suddenly grows a bunch of arms and begins to destroy the city. Uncle Grandpa states that when the UG RV self destructs it destroys everything in the world before it does.
Uncle Grandpa sets to disarm it as he rides on Giant Realistic Flying Tiger with Pizza Steve and Mr. Gus. The first arm is chopped off when Uncle Grandpa uses Pizza Steve as a ninja star. Mr. Gus hops off of Tiger to hold down the second arm to prevent the RV from moving anymore. Uncle Grandpa goes into battle with intent on taking out the rest of the arms. With the help of Belly Bag, he is able to destroy all of the arms successfully. The RV goes back to normal and Uncle Grandpa comes tumbling out of the RV.
Uncle Grandpa reminds them about the mystery dates they had set up and claims that if they hurry they'll be able to make it. The date took place at Fancy Food Market, and they all sat impatiently waiting for their dates at the table. They all angrily complain about being stood up before their dates come walking through the door. It turns out their "mystery dates" were actually just dates with duplicates of themselves.
- The Fancy Food Market resembles the Olive Garden.
- The hand with a glove looks like the one on famous Disney character Mickey Mouse's hands.
