For UK fans, Carol Vorderman was in a box for a Bushtucker trial where her feet were bare and a crab brushed past her feet and she claimed "That tickles" Not sure if anybody can find a clip of it?
I thought it was her, but the edits were so quick I couldn't tell if it was her, Lisa Snowden or Sam Quek. I'd have been happy with any of them, but knowing that Vorderman is ticklish makes the world a better place!
