A man sees a funeral going back. Two hearses followed by a man walking a dog and long, single file line of men behind him. The man goes up to the guy with the dog and says, "I don't mean to interupt your grief, but would you mind telling me what is going on?" The man with the dog says, "Well, my dog attacked and killed my wife. She's in the first hearse.". He pauses for a second, and says, "My dog attacked and killed my mother-in-law." The man says, "Wow, I'm sorry to hear that. Could I borrow your dog for a weekend", to which the other man replies, "get in line".
