There can’t be many executive toys that were thought up by TV continuity announcers. Whither Paul “first on Four” Coia’s eight-ball decision maker, for example? Or Colin “Granadaland” Weston’s magnetic art sculptures? They don’t exist, of course, and quite rightly so because the notion of someone designing a desk-bound plaything whilst cueing up some witty introduction spiel for that night’s episode of Z Cars is, frankly, ridiculous.
