The guy on the uSwitch adverts has the biggest mouth in the WOOORLD. I swear. Whenever that advert comes on I have to mute it because it get stuck in my head for hours afterwards otherwise. A bit like the themetune to Mona the fricking vampire. Urgh. But I still find myself transfixed by the gaping black hole of doom. The adverts on Dave seriously scrape the barrel dudes.
