   If you apply a force to a gyroscope other than through its centre of   
   gravity, then you will be applying a torque. The angular momentum of a   
   gyroscope changes in the direction of the applied torque, so there is   
   nothing unusual about its behaviour. It looks odd only because humans   
   are not used to taking angular momentum into account.
