A man visits a theatrical agent, claiming he has a talking dog. "Show me!" says the agent.
The man turns to his dog and says, "Rex, what do you find on trees?" The dog responds, "Bark!"
"Do you like biscuits?" asks the man. The dog says "Yep!"
"What is on the top of a house?" the man next asks. "Roof!" replies the dog.
"That's terrible, get outta here!" shouts the agent.
As they leave, the dog looks up at his owner and says, "Should I have said chimney?"
