Many years ago I did a Skol Lager promotion with a DUKW modified to look like Hagars Viking long boat with mast, sail, and figurehead. we drove it around to various shows and Pub promotions, Whilst base in Hull we drove it over the Humber bridge, we stopped at the Toll, the official asked what is it?..a Viking long boat we replied, ..does it carry anything?....Vikings!, how many are onboard?..none...the official called the control room for guidance, ..He says its a Viking long boat, what do we charge? there were many puzzled officials looking down at us from the control tower through their binoculars, the traffic meanwhile was queing up behind, after much haggling and ...get that thing out of here we got away with a car rate charge !
