THE FISH IN THE TOILET BOWL

One day a man went into the toilet only to discover that fish were swimming in the toilet bowl. The fish came from the River Ug down below. This river flowed upwards and led into the Thames at Barking Creek. Because of this the man had to wait until all the fish had flowed down back into the River Ug.
The River ug was a river that ran for 20 miles.
