So many.....
Moved into flat with DP. Tiny bathroom, large Dp. First day there, he went for a tricky poo and pushed his shoulder against the shower screen so hard, mid strain it came off the wall, crashed corner first into the bath tub and left a great big hole on the tub. We had to buy a fiber glass boat repairing kit from amazon to fix it. It worked though, we got our full deposit back.
There was also the river of poo incident. Same flat, came back from Christmas at his parents to find that the sewer had backed up with litres of shit all over our garden. Our landlord had gone on holiday to Egypt for a month without telling us so our house stank of shit for weeks before it could get sorted.
All quite scatalogical I'm afraid.
Oh, and the time the kitten managed to eat half a tub of butter and puke all over the house, of course.
When I still lived with my parents, our cat came home holding a live mouse. My mother panicked and tried to wrestle it from the cat. The mouse escaped and dies somewhere in our house but we couldn't find the damn thing for months!
DP trying to put up a shelving unit in our beige carpeted living room. Rested his half opened can of Pepsi on said shelves (he did that thing where you crack the ring pull half open) then accidentally knocked it flying. The can fell in the floor and started spinning wildly, covering the whole room in tiny sticky brown droplets.
The time our cat climbed in through the window and landed on a pile of dirty dishes left on the draining board, smashing them all over the floor.
MIL trying to open a bottle of red wine without a corkscrew and smashing the entire thing on the kitchen floor.
Leaving the roof window open during the snow. That one was me.
When I was at uni I had a pet frog. I used to buy tubs of live crickets to feed it. One time I accidentally put my laundry down on top of the plastic box. I didn't notice for hours and ended up with - 100 escaped crickets in my room. Some of them were noisy fuckers too and I never managed to round them all up.
