Wet behind the ears?

I saw a tv ad this afternoon that had me rather bamboozled – it was for a hosepipe (I think it magically expands during, and shrinks after, use). The product benefit seemed quite intriguing – but, hold on a minute – it’s September on Monday. I became more perplexed when I considered that I was watching the ad in Scotland. Do I evenĀ know anyone who owns a hose?
