Nowhere Man

Mummu and a monk were standing together in the room a little later.
Mummu asked the monk, "Where are you?"
The monk answered, "I am here, Master."
Mummu sent the monk into the other room and asked him, "Where have I gone?"
The monk answered, "You have gone nowhere, Master."
Mummu replied, "Wrong, you are nowhere."
And with that Mummu closed the door between them and left the room.
