Dave is caught cheating
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Dave places the pea on a tennis racquet, which he uses to propel the pea into the air. He immediately loses the pea in the grass, and asks Alex for another one, insisting that it’s for eating, not for the task. Alex is suspicious, and says that he will mark the new pea, to be sure. After Alex gives Dave the second pea, Dave pretends to eat it, then turns his back to the camera and miraculously ‘finds’ his missing pea wedged into the strings of the tennis racquet. He throws the racquet along the red carpet, and manages to get the pea to travel 12 metres and 11 centimetres. In the studio, Greg asks Dave if he’d cheated, and he denies it. Alex then shows footage which reveals that the pea was not wedged into the tennis racquet, like Dave claimed it had been. Thinking on his feet, Dave then claims that he’d been using the racquet to sweep through the grass, while looking for the pea, and so that must be how the pea had subsequently gotten wedged into it. Greg doesn’t believe a word of it, so Dave is disqualified for cheating.
