Boris Johnson caught on zipline

Mr Johnson was featuring as a “special guest” in Victoria Park, London, to ride the zip line, donning a hard hat and two Union flags as he attempted to sail down.
Instead, he ground steadily to a halt on the wire about 20m from the end as the wire sagged, and was left dangling inelegantly in front of a watching crowd.

The Mayor spent around five minutes hanging from the drooping line as spectators took video footage and photographs of his mishap.
When one asked how he was feeling, he replied “very, very well thank you”, before shouting: "Get me a rope, get me a ladder" to bystanders.
According to eyewitnesses, he spent the intervening minutes waving his flags and leading the audience in cheering on British gold medal-winning rowers.

Eventually, staff came to his rescue and used a rope to tow him to the bottom of the line.
The cause of the incident has not yet been confirmed, but it is understood to be down to a "loss of momentum" as the wire sagged lower than expected. Other visitors to Victoria Park are believed to have since used it successfully.
A spokesman for Mr Johnson told reporters he "remained unbowed" by the incident, adding: "The judges will rightly be marking him down for artistic impression."

This guy is a right tool.
