Moved my foot and the fucker jumped about two to four inches into the air. Thereby moving closer to said foot . Probably closer to two than four. No matter. It startled me! I snatched up an empty gallon jug of vinegar that happened to be sitting there (I'm soaking a shower head in the stuff) and brought it smartly down upon said jumpy big black or brown spider, expiring it rather expediently.
Hate to kill anything that kills and eats bugs, but that old boy looked like it could bring a small field mouse down and seemed to be jumping in my general direction. It hadda go!
