Football's a decent enough game. It's a lot better when someone can zap you mid-run.
Shock Football puts ten shock devices into play, so every sprint, tackle and shot on goal comes with the risk of a sudden jolt.
Cue an awful lot of very theatrical falling over.
Your event coordinator runs the session as referee, explains how it all works and hands out the coloured bibs and cones so you know who you're meant to be passing to.
You'll get around an hour of game time, with up to twenty of you battling it out. Long enough to settle a score, short enough that nobody's legs pack in completely.
The best bit is watching the stag line up a tap-in and crumple before he's got anywhere near the ball!
It's daft, it's competitive and it turns even the least sporty person in your group into the main event, which is exactly why it lands so well on a stag do, a birthday or a team day out.
The set-up travels all over the country and runs in sports centres, indoor halls or on outdoor pitches, so wherever your lot are based there's somewhere to play.
Everything you need is provided and waiting when you arrive. You just turn up in something you can run in.
And it finishes with a group photo, taken while everyone's still red-faced and arguing about who dived.
So, who reckons they can keep their feet?
