Goat-insects are commonly thought to be a goat/insect cross, but in actual fact are a sheep/insect cross, hence the white fluffy coat. They where originally bred by Mi5 as an experiment to see if stick insects could be farmed for wool, but due to pressure from the welsh farming community the experiments where dropped and the test subjects released into the wild. The mojority released died from an insect equivelent of syphalus, but a few still remain in a small community located in Exeter, in the hedgerow of a small rural primary school. Local people are now threatening there existance by harvesting them to use as fire lighters, the RSPCA have declared the area a SSSI and are in the process of setting up a breeding program to ensure the goat-insects future.
In Scotland, the addition of an exclamation mark instantly makes things funny! However, the original exclamation mark-shaped plans for Hadrian's Wall were cancelled when it was realised nothing was holding uo the top bit.
My ancestors were from Scotland, but spelled their names with a question mark at the end. This led to confusion, vast intermarriages, and, ultimately, extreme difficulty in genealogy searches.
As a subtle practical joker, I like to cover my local zebra crossing with a life size negative photograph of it, and count the years til anyone notices.
