This guy comes home from work one day to find his dog with the neighbor's 
pet rabbit in his mouth. The rabbit is dead and the guy panics.
He thinks the neighbor is going to hate him forever, so he 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 guy,
"Did you hear that Fluffy died?".
The guy stumbles around and says, "Um.. er.. no.. 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!"
