Many years ago, a Friend's father-in-law bought a new boat and wanted it ready for a yacht race starting at 10.00am on Saturday.
The boat, a trailer/sailor only arrived on the truck at 3.00PM on Friday afternoon.
The whole crew were assembled and allocated tasks to step the mast, bend on the sails, fit out the interior etc..
One crew member was instructed to go to the hardware store and get any sign, lettering or what-ever so that any name could be placed on the boat in accordance with the race rules.
As a result the boat became called "BEWARE OF THE DOG"
