Cone...

Head!

The Duke of Wellington (eponym).

Posturing on his horse, hand on hip, chest puffed - saying "look at me world!".

Well we will, cause you've got a cone on yer heed ya dafty!

Glasgow folk put it there, council take it down - and on and on the game goes. Think they (the council) just leave it now!

Thanks Grand Old Duke of Wellington
