There are two brothers, Sam and Dean. Sam asks Dean to to watch his house and cat while he is away on vacation. After a few days, Sam calls Dean.
"Hey, how are things? House still standing? How's my cat doing?"
Dean swallowed hard, "Well yeah man, your house is still standing. Sorry to tell you this, though, but your cat died."
"What?" Sam said. "You just can't tell someone that his cat is dead. You have to break it to him gently. You should say that the cat is on the roof, trying to catch a bird."
"So," Sam continues. "How's Grandma?"
"Well, Grandma's on the roof."
