Station, Train Station
A horse and a shrimp are sitting next to each other. They are both at the train station, waiting for a train to come and take them home.
Imagine the horse and the shrimp sitting next to each other on a small bench. There is nobody else at the train station. It is awkward.

The train pulls into the station. They walk up to the train doors, but they don't open. "Perhaps a key (えき) would help?" asks the station master, as he goes over to open the door to the train.
Instead of saying "a key" he says "eh key." How strange. Imagine the station master saying it like this with his weird accent. You ask him if he has "a key" and he replies with, "What is a key?" Then you say "eh key." He totally understands you now.
