Two mates walking their dogs on a nice sunny afternoon.
After a while they come across a pub, one of the guys, says to his mate, "how about we go over and have a drink?"
Is mate replies, "We can't go in the pub with the dogs."
Watch, says his mate. He then pulls out his sunglasses and tells his labrador to go over the road and into the pub. The bar man asks him what he thinks he is doing?
"It's my seeing eye dog" he replies.
Upon witnessing this, his mate puts on his dark sunnies and walks over with his dog.
The bar man proceeds to ask him what the hell does he think he is doing?
"It's my seeing eye dog" he replies.
The barman yells at him, "It's a chihuahua!"
The reply, "A chihuahua, a chihuahua. I've been dudded, they gave me a chihuahua!"
