A highly timid little man, Casper Milquetoast, ventured into a biker bar in the Bronx and clearing his throat asked, "Um, err, which of you gentlemen owns the Doberman tied outside to the parking meter?"
A giant of a man, wearing biker leathers, his body hair growing out through the seams, turned slowly on his stool, looked down at the quivering little man and said, "It's my dog. Why?"
"Well," squeaked the little man, obviously very nervous, "I believe my dog just killed it, sir."
"What?" roared the big man in disbelief. "What in the hell kind of dog do you have?"
"Sir," answered the little man, "it's a four week old puppy."
"Bull!" roared the biker, "How could your puppy kill my Doberman?"
"It appears that he choked on it, sir."
