The correlation you may have noticed between the plumber's visit and your wife's fanny size increasing markedly is far from spurious and is a direct cause and effect phenomenon.
What about if I told you that the chaps who serviced the boiler also fiddled around with the stopcock while they were here?

Also, you've essentially ignored my original question which was about the loud gurgling noises emanating from our plug holes that pre-date the unfortunate knickers-flushing incident by several weeks.

What's causing that?
