Les chroniques de St Mary, tome 9.7 : and now for something completely different

Here's a question for you. What's the most exciting thing ever found in a fire bucket? And don't say 'fire' because you'll be wrong. Suppose - just suppose - it was the technology to take a pod to Mars? Yeah, now we're talking! Every Christmas, for reasons which seem good at the time - especially after an eggnog or two - Max and the others leap into the nearest pod and indulge in their illegal Christmas jump. It's a tradition. This year, however, just to be different, they find themselves part of someone else's illegal Christmas jump. It's time to don a spacesuit and bring your own urine!
