We have always considered doing male WAN with the dunk tank. We have it filled next week and are looking for 1 or 2 guys 18 to 30 who fit the role of Dunk the Hunk to be filmed being dunked. This is a test shoot for us do there is no money available but you will have the chance to be dunked in 1500 l of Gunge. If you are available next week and can get to Heathrow then get in touch.
I'm available and close to Heathrow. I'm older than your age range but happy to volunteer. Email me at email@example.com if you're interested, and let me know what you need me to bring if you are. No worries if I'm too old for you, I'm not a young guy and I'm happy with who I am.
