Stay Safe... Wear a Wig
As someone who actually isnt completely sure what his head would look like with hair, what with having shaved the lot off for over a decade, why is it always the bald bloke who gets it in these signs?
Its not as if we are any more clumsy? Or are we risk taking adrenalin junkies who get ourselves into situations more often than people who worry about ruining their spikey tart confections on their heads?
Anyway, sod the hard hat... wear a wig!
(Or stand next to a bald bloke)
