You know when you're a young kid and you go and visit a friend for a play date, and you get stuck in his bathroom because you don't really understand the new lock system that you don't have at home?
That's a bad one. A difficult one to get over. However, back then video phones weren't at hand to capture the sickening panic that envelops you.
Spare a thought for this lad in Belfast, then, who managed to get locked in one of those claw-based arcade games in a local supermarket. He has been chosen!
