Your dog?
--------

A man went to a pub with his Great Dane and when he arrived, he tied the
dog up outside and went in to have a beer.

A few minutes later, another fellow walked in and said, "Is that your dog
outside?"

"Yes. What of it?" said the first man.

"I'm sorry, but I think my dog may have killed him."

"What kind of dog you got that can kill a Great Dane?" said the first man
stunned.

"Well, he's a Chihuahua."

"Ha! How can a Chihuahua kill a Great Dane?"

"I think he may have gotten stuck in his throat." said the second man.
