A sleeper is one who sleeps.
A sleeper is that in which the sleeper sleeps.
A sleeper is that on which the sleeper runs while the sleeper, sleeping in the sleeper, sleeps.
Now if the sleeper that carries the sleeper over the sleeper under the sleeper, jumps the sleeper,
It will wake the sleeper, sleeping in the sleeper, by striking the sleeper on the sleeper.
