Best possible team building exercises were explored by South African rugby during the preparation for the 2003 work cup, the fabled Kamp Staaldraad system. Some of the highlights include:
* The team was ordered to climb into a foxhole naked and sing the national anthem while ice-cold water was poured over their heads. During their time in the hole, recordings of God Save the Queen ( England's national anthem) and the New Zealand All Blacks haka were played at full volume.
* It was confirmed that firearms were present at the camp, although reports varied as to whether they were ever pointed at anyone.
* The players were forced to crawl naked across gravel.
* They also were ordered to spend a night in the bush, during which they were to kill and cook chickens, but not eat them.
Hahahhaha, awesome.
