Tom's cooking for Matthew's sister Rachel as it's her birthday, but unfortunately, Ben's changed the channel on the telly from the cooking programme Tom was following and now it's a nature show - the food is going to be a disaster!
Meanwhile, Ben's not overly keen on the course Matthew's making him do, nor his flatmate's insinuation he's an academic failure! So how will he fair with a tank full of stick insects to monitor for a week?
With a banner in place (reading Happy Birt), a makeshift disco ball hanging from the ceiling, stick insects on the loose, and Tom's seafood, chocolate and cherry lip balm chowder on the boil, what could possibly go wrong?
