Blind bloke walks into a department store...
...with his guide dog.
He makes his way to the middle of the ground floor, then carefully lays down his white stick, and picks up his dog, which he then begins to swing -by its tail- in wide, sweeping circles, above his head.
The Department store manager is most alarmed to see this behavoiur in his store, so he (carefully) approaches the blind man.
"Is there anything I can do to help you, sir?" he asks...
"Not really" replies the blind man, "I'm just having a look round!"
