A man walked into a pub with his dog.
The landlord said, “Sorry Sir, but no dogs allowed.”
Not wishing to leave, the man said “But, I’m blind… he’s my Guide Dog”.
The landlord looked doubtful and said, “But it’s a Yorkshire Terrier.”
The dog owner put on a look of amazement and said “You’re joking! They told me it was a very small labrador.”
