Bad Dog, Put Fluffy Back
This girl comes home from work one day to find her dog with the neighbor's pet rabbit in his mouth.
The rabbit is dead and the girl panics. She thinks the neighbors are going to hate her forever, so she takes the dirty, chewed up rabbit into the house and gives it a bath, blow dries its fur and puts the rabbit back into the cage at the neighbor's house, hoping they will think it died of natural causes. A few days later, the neighbor is outside and asks the girl, 'Did you hear that Fluffy died?' The girl stammers and says, 'Um...no...um...what happened?'. The neighbor replies, 'We just found him dead in his cage one day, but the weird thing is that the day after we buried him we went outside and someone had dug him up, gave him a bath and put him back into the cage. There must be some real sick people out there!'
