All I can do is howl with laughter! I have NOTHING that tops that!
But, here is one.
This was with my first husband.
As a preliminary, I should note that there is NO ONE on this planet who hates spiders more than he does.
The first incident: He walks into the house through the front door, looks down, picks up a large planter with an aloe vera plant in it, tosses it into the middle of the living room rug, and jumps up and down on the plant and dirt screaming, "It won't die! It won't die!" Baffled, our son and I asked him what the aloe vera plant had done to deserve execution in this manner, particularly since it was most certainly dead at that point - not to mention the rug! He pointed at a small object in the dirt. Our son pointed out that it was a black plastic spider ring that he had gotten for Halloween.
The second incident followed several days later. My former husband walked into the kitchen area of our great room and came up behind me. He immediately jumped backward, pointing his finger, and shouting "Ooh, ooh, ooh, ooh!" I asked what the problem was. He pointed and said "Ooh, ooh, ooh, ooh!" I looked and saw a very, very large tarantula spider on the counter which had just emerged from between two cannisters. Apparently, he saw it, thought it was a plastic spider (see first incident), and was going to shove it in my face to scare me.
He demanded a fly swatter. I immediately produced one. Halfway through his swing, it dawned on him that the swatter had a reach of 18 inches and the spider had a jump range of about 6 feet. He flung the swatter on the floor and stormed out of the kitchen.
He reemerged from the back of the house seconds later with a BB gun. He took aim and blam, blam, blam, fired 3 BBs at the spider. The spider dissolved into a pile of green goo, while the refrigerator still shows the 3 BB marks.
I had been calm up until that point. Then I began to jump up and down and scream.
We still laugh about this. Talk about insanity.
Did I mention that he WOULD NOT go see the movie "Arachnophobia."
