Driving my daughter to her swimming lesson this morning, I asked “So what are you doing today then?” “It’s ‘locate and rescue’ today.” She said, “We’ve to dive under and grab a rubber brick from the bottom.” I said “You’re going to have to hold your breath for a good while.” “Why, is it hard to find?” She asked. “No idea.” I said, winding up the windows “But I’ve just farted.”
