I think it’s a spinoff of Eurotrip when they stay at a hostel.

Hello, and welcome to Amsterdam’s finest and most luxurious youth hostel. We feature one medium sized room containing 70 beds which can sleep up to 375 bodies a night. There is no bathroom. Nor is there one nearby. If you do not wish to have your valuables stolen I suggest destroying them or discarding them right now. You can also try hiding your valuables. In your anus. This will deter some but of course not all thieves. Once you are inside, the doors are chained and locked from the outside. They will not be opened again until morning, no matter what. Should a fire occur due to our faulty wiring or, uh, the fireworks factory upstairs you will be incinerated along with the valuables that you have hidden in your anus. Tips are greatly appreciated.
