Rach and Em get together for a funnelling challenge and you know how much these girls love to compete, especially if there's food or chocolate milk involved. In this clip they go against the clock and each other to see who can down 1 litre of ice cold, chocolate milkshake the fastest, each taking time to enjoy and appreciate the others soft, full belly in between gulps. The result is quite a shock to the girls, they never expected there to be such time difference!
