Dev - What Horse-based fun could Dev do?

What Horse-based fun could Dev do with Pulled Apart By Horses? Pulled Apart By Horses are Dev's Record of the Week. Dev & Prod P wonder what mildy amusing horse-based ideas they could rope the band into? Also, Dev's in for Vernon on Saturday mornings until Christmas. They always get loads of guests on the show, though some of them are quite random bookings. Do they just pull names of celebs out of a hat? Dev tests out this theory with his own 'Guest Tombola'.
