Telephone Exchange
Upto 20 players can take part at one time. Each player goes down the course holding a velcro telephone number. You leave the phone box, climb the wall, go over the phone wedge, fax yourself through the fax machine, weave through the fax rolls, and then leave your velcro number on the inflatable phone box at the end. A quick dash back to the start to tag your team mate, and the he or she takes the second number, and so on. The tenth player arranges all the numbers on the phone and brings the yellow pages back through all the obstacles. The winning team is the first to get the yellow pages back to the start.
Better still, the idea behind the telephone exchange can be adapted to suit whatever kind of business you are in.
