This week, Harry invites an often bemused but nonetheless game Joey Essex on to his teatime show, to embrace a children's theme. The pair make savoury envelopes using popular crisp brands (an exercise that betrays Joey's unfamiliarity with the inner workings of the post office); a series of chocolate crispy Unesco world heritage sites; and a replica of Sesame Street's Elmo from sweetcorn, paint, Solvite and scotch eggs. It is, as ever, a delight.
