[P/O W. 'Moggy' Cattermole]

You must river dance to the Benny Hill theme music whilst dressed as Grenadier Guardsman on top of Tower Bridge, backed by 40 men in the napoleonic uniform of the 42nd Blackwatch Highlands regiment, divided into two ranks of 20. They must also be doing the riverdance. However, the tartan on their kilts must alternate between Clan Fraser and Clan MacDonald, and they must all be facing directly at you. You have to get it just right or it won't work. You must be facing the river from the left hand side of tower bridge as you go leave the Houses of Parliament, and the backing dancers must be behind you. Policemen in the traditional British Bobbies' uniform must perform cheerleading routines on the flanks of the highlanders. Do this and I absolutely guarentee you'll get your rain.
