Monkey's advent calendar: Glasto giggles on Radio 4

Eight days after we brought you BBC Radio 4's Today presenter Evan Davis getting a fit of the giggles over an MP's duck house – what do you mean you didn't open door number two? – we return to Monkey's file marked "Radio 4 types who crack up on air". This time it's Tomasz Schafernaker who suffers an unfortunate turn on air while reading out the weather forecast for the Glastonbury festival. Eighty per cent chance of precipitation. A hundred per cent chance of a smile.
