Posting in a legendary thread!
I once long long ago smashed a biiig fat black fly clear across the hobby room where I had my now ancient Amiga set up using the top half of the casing of said Amiga.
It came buzzing towards me - WHAMMMO! Straight on the noggin!
It flew straight back the way it came and fell to the floor, on its back. Apparantly I'd damaged it internally because a tiny pale yellow drop of something (probably unmentionable) had pushed forth out of its rear end.
Despite this it regained mobility and tried to leg it. Not so. I promptly squished it.
In my youth I worked summers in a pharmacy where some sensitive goods had to be stored in a refridgerated space. Apparantly no place is safe from flies - not even pharmacy cool rooms. So I found myself in that enclosed space with many empty boxes of wares I'd just unpacked - and what appeared to be one common housefly buzzing around.
I thwacked it with a small empty cardboard box and it crashed to the floor. On its back.
Again, it seems I'd busted something inside it, because apparantly it did not understand it was lying upside down. Or that one of its wings was poking straight out to one side while the other was folded down along its body.
Hilarity promptly ensued when the fly decided it was best to take to the air again - which only had the result it started spinning round and round and round on the spot - extremely qucikly!
"BzzzzzZZZZZ!" went the fly - figuratively speaking - probably rotating at 1000+ RPMs, so fast it only became a fuzzy blur. Then after spinning for several seconds it must have realized something was wrong and turned off its wings and stopped rotating.
I myself was laughing almost hysterically at the sight, so feeling embarrassed it decided its ego could take no further bruising and tried to fly away again. Only to start spinning again!
Of course, all the fun ended with the fly getting squished..
Maybe I sohuldn't mentino that time during my childhood years whenthe basement store room became a fly hatchery and a hundred big fat flies buzzed out of there. I won't mention either the disgusting meaty "tink!" noises they made from their chitin carapaces impacting while bouncing down the aluminum tube of the vacuum cleaner when I sucked them up either..yeeech.
Peace.
