I used to live in a street called Duke's Meadow. Meadow was about right - the land was low-lying and damp - but this was rural Wales, so there were no dukes for miles around.

Now, 'Duck' is a good old English surname, going back to the Norman Conquest on some accounts. Bear in mind also that 'bottom' meaning 'bum' or 'posterior' is a relatively recent euphemism - 'bottom' used to mean no more than the lowest part of something, & often referred to a low-lying field.

And so it came to pass that a row of houses was built on a plot of land called Duck's Bottom...
