A man goes to a bar and he ties his Great Dane up outside. About 10 minutes later a lady comes in and asks whos Great Dane is outside.
"Mine" says the man. "My dog has just killed him", she says.
"What breed is your dog?" he asks. "A Chiuahua", she says.
"How can a Chiuahua kill a Great Dane?"
"He got caught in his throat!!!"
