as a special guest in Victoria Park, London, Johnson decided it was a good idea to ride the 1,050ft (329m) zip line. He donned a hard hat and waved two British flags as he attempted the ride.
As he sailed
along he was heard to say, "This is great fun but it needs to go faster."
Then, to the bemusement - and probably great amusement - of the watching crowd, he ground to a halt on the wire, approximately 65ft (20m) from the end of the ride.
The Mayor of London then spent about five minutes, hanging from the line, as spectators took video and photographs of his rather embarrassing stunt.
asked by one of the spectators how he was feeling, he said, “very, very well thank you”, and then yelled: "Get me a rope, get me a ladder."
When asked how the Olympic Games were going he said, “It’s very, very well organized. It’s going well so far. Right.”
