Dorm number 7 on Ziemniaczana Street was a place where nobody slept before midnight and sandwiches disappeared faster than microwave pops. Zuza, a third-year architecture student, and Kuba, who was switching from sociology to management at the speed of light, shared a common addiction: absurd humour and late-night snacks. One very dull evening, when the grapes in the fridge were starting to ferment suspiciously and the TV was only showing reruns of a series about cucumbers on a trip around the world, Zuza sighed: - 'We need to do something crazy. I can't look at these boring yellow cheese sandwiches anymore. Cuba looked at her with a glint in his eye: - How about... A Night Sandwich Club? But not the usual kind! We're going to search for the weirdest sandwich compositions all over the dormitory and test them on each other! - And judged on a scale from "Oh, no!" to "Long live the Sausage King!" - added Zuza enthusiastically. So they posted a notice quietly on the board by the lift: "We are looking for volunteers with sandwiches beyond imagination. Sandwich Night Club - tonight at midnight, room 303 - slogan: 'What's on top is on the inside'." Seven people came in at midnight. Each with a sandwich that broke all the rules of food preparation established by mankind. There was a herring and banana sandwich (shy Asia from the fourth floor), a sandwich with pate, nachos and mint tooth gel (Bartek, who supposedly hadn't slept for three days), and the legendary 'Bread with air' (no one wanted to touch that one). There was no end to the laughs. Zuza tried to swallow a piece of Bartek's experiment and for a quarter of an hour felt like her tongue was colder than strawberry ice cream. Kuba, on the other hand, after nibbling on a sandwich with pickled cucumber and peanut cream, found that his soul had left his body for a moment to pity him. The fun continued until suddenly Basia - a quiet girl from medicine, known for her sandwiches always being sliced perfectly evenly - burst into the room. This time she had a look on her face as if she had seen a ghost in the fridge. In a hushed voice she said: - Someone... someone left a big bag outside the dormitory door... with something I can't describe. It's so heavy that I barely brought it in. And... and it's clearly moving. Everyone fell silent. Even Bartek stopped munching nachos for a moment. They looked at each other. The mystery bag, the night, the middle of the week and the Night Sandwich Club - what could have gone wrong? They walked the bag to the middle of the room. Zuza put her hand on the zipper. Everyone held their breath...
