Join Jonny K for his first time on the Dunk Tank where he plays Dunkety Dunk with Hayley. Jonny gets dunked lots of times into the thick green gunge going under every time. Jonny loves the gunge and has a great time being dunked. The gunge is the thickest its ever been made and Jonny certainly puts it to good use. Jonny loves it so much it doesn't take hime long to lose the singlet and be dunked naked.
