Doggone Tired (S)

It's nighttime. A hunter and his dog arrive at the Happy Hunting Lodge. The hunter tells the dog: "Don't worry, we'll get up at five in the morning and really blast a bunny. You'll never catch that rabbit unless you get a good night's sleep". The bunny overhears and is hit with an idea. He won't let the dog get a good night's sleep -- or any sleep at all.
