How about a H & V Grand National sweepstake, no money but just for the fun of it ?
How might we organise it?
Easy.
Right, I've randomized the horses on a document on my PC.
Pick a number between 1 & 44 (to include the reserves, tough if you don't get a runner) and I'll tell you which hoss you've got, I'll take the last one left unless someone pips me to it before I get chance to nick it.
