Two friends, Jim and John, were walking their dogs

...when they passed by a restaurant.

*"Let’s go in and get something to eat,"* Jim suggested.

*"We cant"*, responded John, *"don't you see the sign says NO PETS ALLOWED"*

*"Aah that sign,"* said Jim, *"don't worry about it"* and taking out a pair of sunglasses, he walked up to the door. As he tried walking into the restaurant he got stopped at the door,

*'Sorry sir no pets allowed'*

*"Cant you see"* said Jim, *"I am blind, this is my seeing eye dog."*

*'But it’s a doberman pincher, who uses a doberman pincher as a seeing eye dog?'* the man asked.

*"Oh!"* Jim responded *"you must have not heard, this is the latest type of seeing eye dog, they do a very good job".*

Seeing that it worked, John tried walking in with his Chihuahua.

Even before he could open his mouth, the doorman said *'don't tell me that a Chihuahua is the latest type of seeing eye dog.'* Thinking quickly John responded in a angry voice *"You mean they gave me a Chihuahua?"*
