Social media company Fresh Networks of London pulled off a PR stunt earlier in the week: hijacking 24 Boris Bikes and supplying them to 22 Santas (and two besuited reindeer).
Charlie Osmond of Fresh Networks said:
"Tourists thought we were delightful, cabbies called us a menace and the police tracked our every move – convinced that, at any moment, we might start a student protest.
"With mince pies in our bellies and iPhones strapped to our Boris Bikes we tweeted all the way to Buckingham Palace; arriving just in time to catch Prince Philip who stopped his car to ask what we were up to and to wish us a Merry Christmas all round."
