The butt of jokes

I have collected the 220 litre water butt from Nick (plot 15). A cracking bargain at £15 including stand, taps, diverter and childproof lockable lid. Once the girls had finished making jokes about seeing my butt and the size of my butt etc. they said it would make an excellent plunge pool or hot tub. Now there's an idea for a Summer evening after a day of graft on the plot!
