Talking of exploding rodents…….
When I was a teenager, we lived out in the countryside, and our house was set back from the road, down a track which became nigh impassable if it was icy or snowy, so dad used to park the car by the church. If the car wouldn't start, mum, dsis and I would push the car off down the hill, while dad bump started it.
Well - one snowy morning, the car wouldn’t start, so dad bump started it, and we set off (he used to drop us at school on his way to work). Although he’d got the car to start, there was clearly something wrong - it just wasn’t pulling properly. After he dropped us off, dad was on his way through a small town, when there was a big explosion under the car - which then started to pull properly.
Dad pulled over to see what had happened, and the car behind him pulled over too - with a shattered windscreen. Turns out that, when dad parked the car the night before, he’d parked up against a snowdrift, and a rat had crawled into the nice, warm exhaust pipe, and got stuck there. Once he started driving the next day, the rat gradually cooked in the exhaust until it had shrunk enough to come out with all the pent up power of the trapped exhaust behind it - and the cooked rat projectile had gone through the windscreen of the car behind, and splattered all over his back seat.
He was very understanding, and laughed it off, saying it was a company car, and he would scrape the bits up and send them to the people who did their insurance.
Dad dined out in that story for the rest of his life, and I am following in his footsteps.
