During iCarly, Sam gets a text that her mother, Pam, is being held in a Las Vegas jail, and her lawyer informs her that she needs $2500 to bail her out. Spencer suggests going to Las Vegas and pawning things to get the money.
In Las Vegas, Freddie tries to sell a vintage computer to the Pawn Stars guys and Carly and Sam try to sell a bottle of WaHoo punch Michelle Obama drank from and signed. After explaining their situation, they get the $2500 they need and put the money in a bag with Gibby's fake head. However, just as they are about to leave, Gibby goes to the back of the store to sell his pants to Chumlee without the others noticing, so he gets left behind.
Before the others realize Gibby and the money are missing and return to the pawn shop, a man distracts Gibby with a "moon rock", which is really just a random rock from the parking lot, and steals the money. Luckily, a little asian girl wants to have Gibby's fake head, and her father offers them $10,000 for it. Gibby refuses to sell it, but Sam uses the Vulcan Nerve Pinch to render him unconscious. Once they get back to the RV, they realize Spencer isn't in the front seat to drive them, but singing in the shower.

- When the Carly tells Freddie to bring up the map, you can clearly see in the first shot that there is already a pin in Nevada. But when they go back to it in a future shot, you can see that it's not there and they are adding the pin.
