The wrong kind of vacuum cleaner
On this occasion, the family alsatian had produced a massive puddle of diarrhea right outside my younger brother's bedroom door. It was brown, soupy and had a diameter of about 18 inches. I was there to witness the look of horror on my brother's face when he first saw it. I had to dash off to work, leaving my sibling to deal with the mess.

When I came home at 5 o'clock, there was not a trace of it to be found - all gone. I asked my brother how he had cleaned it up. 'I used the Hoover,' was his reply. As in, the brand new, upright Hoover (with paper dustbags) that our mum had bought a couple of weeks previously. 'You're joking?' I asked. He shook his head. I fetched the Hoover from the cupboard and opened it up. There was the sodden dustbag, oozing doggy discharge and stinking to high heaven. I turned the machine upside down and, sure enough, the brushes were all coated in a sticky brown sludge. I think he must have thought that all vacuum cleaners were the same and that, just like the Vax cleaners he had seen advertised on TV, they could all handle 'liquid' spills.

Despite stripping the Hoover down and soaking the parts in disinfectant, every time it was used thereafter left the house reeking of dog arse. It ended up in a skip.

Bleh.
I wrecked my mum's dustbuster, attempting to dispose of a cherryade spill. More fragrant than dog shit, but the overall effect was the same.

I have learned from this QOTW
that dogs are vile and pointless creatures.
