This was TV joy at it's best, and no way was Gaffney acting, unless he can spontaneously vomit at will.
Basically, he came on screen looking really, really confused, didn't know he was on live tv, and couldn't understand that the viewers had voted him in. He was then told he was going to do a trial, and started totally flipping out, hyperventillating and vommiting (off camera during the break). When we came back he was still utterly panic stricken, but worked his way through several horrible insect/rat infested trials, screaming and retching the whole time. I thought he was going to kill some of those baby crocodiles with the amount of thrashing he was doing in the pool. Highlights -
"Ahhh, I'm bleeding" "It's only a scratch Dean, you'll be okay"
and of course his glorious exit, where he disappeared of screen into the jungle, and Ant and Dec tried to do their final link to camera, punctuated by Gaffney shouting 'Help' somewhere in the jungle.
