How have I managed 85 years without a 'bum gun'? What is it for ?, what is it aimed at ? If the motion is properly tapered then there is nothing to shoot at !! Of course, after a nightout enjoying an Indian curry or two then a 'flock of starlings over the chapel roof ' could warrant a thorough hosedown. Secondly , how does someone with a 3xxxl buttock manage to get the 'bb' into position to aquire the target ? We have a 'bb' in each of our bathrooms and I use it to blitz the odd ant or mossie !!
