Great Dane
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!!!
