A Weighty Problem

[stocksman]

My wife said she thought she had put on a 'bit' of weight but she couldn't see the tiny figures one the screen of our old scales so I bought her a ''speak your weight'' machine.
Two days later I saw it in the bin. So I asked quite nicely if there was a problem with the new scales. She said ''it doesn't tell me my weight, it just keeps saying 'one at a time please' ''.
