yeah..I should probably extrapolate a bit.
I use humour to defuse rages at times, and have honed a rather fucked up sense of the "funnies".
Though I rarely do any of the things Ive posted any more, I have an entire arsenal of ways to bring people to their knees (figuratviely) .
Sometimes admittedly, the humour is purely sadistic , and affords me recompense when all other avenues are closed .
@Tom , hectograph (used for drafting and engineering) can be used to "paint " things. it stains almost anything (steel included) and is a joy to make offensive pictures with. But hey ...paying bums works too.
