A man and his dog go to an entertainments agency.
The agent says; "ok, what do you do then?"
The man says " i have here the worlds only talking dog".
"lets hear it then" says the agent.
"Rover",says the man, "what goes on top of a house"?
"roof roof" replies Rover.
The agent is not at all impressed.
"Rover", says the man, "what is on the outside of a tree"?
"Bark bark" says Rover.
At this point the agent's patience has expired, he grabs hold of
both the man and his dog and proceeds to hurl them down the
two flights of steps leading down from his office.
Laying in a bruised heap at the bottom of the stairs, Rover lifts his head, looks at his master
and says "what the f***s the matter with him then"?
