One the Buses - Christmas Duty - S1.E11

Once again Jack and Stan are in the inspector's bad books for using the bus to collect Christmas presents so, when a husband and wife crew report sick, he has the two men working on Christmas Day. Mum has cooked the turkey but to save Stan walking home Arthur agrees to collect him in the combination. But Arthur has had too much Christmas spirit and Olive agrees to drive, with Arthur and Mum to supervise. Unfortunately she crashes the bike and when they all get home the fire brigade has been called and the turkey is burnt to a cinder.
