Some years ago, a friend of mine decided that, he too, was tired of break ins in his apartment. Being a good California non-violent hippy type sufer dude
he decided to frighten 'em off. On his apartment window he rigged a pull string that would ignite a pack of firecrackers to frighten off a would-be thief. (You can see it coming, can't you?) So late one night, weeks later, he's doing the horizontal mamba with his latest honey when they hear *pop**pop**pop**pop**pop**pop**pop**pop**pop**pop* from the livingroom. Of course by the time he ah...disengages and slips on some shorts, both the curtains and sofa are on fire.
But then, we always did say "he strong like ox, smart like tractor!"
A friend near Tahoe, tired of people breaking into his garage by using channel locks to remove the door knobs set a trap. He used one of those water/air pressure fire extinguishers set to discharge into the door opening if the door was opened. To make it easy to ID the perps, he put in water, a half cup of detergent and half a gallon of fish-emulsion fertilizer! Sure enough, two teens tried to break in and got "hosed" good. He woke up hearing them saying "ahhh S---!" and "what
is this s---?" Cops picked up a pair of smelly & foamy suspects two blocks away and made them
walk back to avoid stinking up the patrol car.
