The two-month campaign, devised by Naked and booked by OMD and Posterscope, involves 50 specially marked Taxi Media cabs in London and free gift-packs for passengers, with headbands, fake moustaches and a free phone card.
The packs also invite passengers to text a donation to 95.8 Capital FM's Help a London Child appeal.
