Of course, the moment we're talking about is when Tony Hadley ignored Susannah Constantine's high five.
To be honest, Tony didn't purposely blank Susannah, he just simply did not see her hand gesture. But it made for great viewing.
The pair had been picked as team captains for the first task, where they would hear the voice of a celebrity talking about themselves on a large screen, where they then had to decide who they wanted to pick.
We reckon it's going to be one of those moments when we'll look back in a few years and ask: "Who remembers that time Tony didn't high five Susannah?"
