Fill it up full of illegal immigrants / Aussie bar workers, hoodies and chavs and give the buggers a free cruise to the Falklands.
Paint it in a colour scheme reminisant of a bad acid trip and Park it up in randomly in inconvenient places like dead centre of the boat lanes during the university boat race or Henley regatta or wedge it under Tower Bridge when its been opened.
