I have been interested in wam for many years now and first came to notice I enjoyed seeing people gunged when as a boy watching programmes like those of Noel Edmonds and the children's shows with gimicks like the 'finger of fate' and the 'gunk dunk' were on. I really, really wanted to be in one of those gungetanks!
These days I don't get much chance to wam but my favorite substance has to be warm porridge. Having your head slowly enveloped in it and then feeling it drip down your torso is one of the great pleasures of my life.
If you have any questions: just ask. http://uk.360.yahoo.com/gungeable
