The old bugger did it to me last week as well.
They're both as deaf as posts and wont wear their hearing aids (coz everything is too loud

No need to bust down the door - a coin will unlock the door from the outside.
Oh, and flushing is a good thing
Gee, Sharyn's knickers get comfy after a while....
