Bob -- I'm so sorry to crush your feelings, but it wasn't me who sent you the chocolates: I think you're getting me mixed up with Ian! Dom.
Are you quite sure Dom?? The card said "from your tall, dark and handsome Valentine" and of course you immediately came to mind.
Seriously, I wondered if they even sold ExLax in the UK and evidently they don't. I see why my little joke went over like a lead balloon. EXLAX is a laxative in the US which can be purchased chocolate flavored in the shape of a candy bar.
I used to work on the production line in a factory and while we employees were working the supervisors hung around the break area eating the goodies we had brought in for ourselves. One day one of the employees brought in a nice cake with chocolate frosting...EXLax chocolate frosting. Needless to say, before long it was obvious who had been sneaking the snacks!!
