Velocity of rocket exceeding the velocity of exhaust gas

It is possible for the velocity of a rocket to be greater than the exhaust velocity of the gases it ejects? When that is the case, the gas velocity and momentum are in the same direction as the rocket's. How does the rocket still obtain thrust by ejecting the gases?
