Mike and Jim had been friends for a lifetime. Growing old, they
promised each other that the first one to die, would try and come
back to tell the other what the afterlife was like. Eventually, Jim
dies and some weeks later, at night, Mike hears a familiar voice,
calling  him, "Mike, Mike!" "Is that you, Jim?", he answers. "Yes
it's me, and I want to let you know that the afterlife is fantastic.
I am having sex non-stop, with a wide variety of partners and  never
get tired." "That's sounds great, Jim", says Mike, "I would have
never thought that Heaven was like that." "I'm not in Heaven, Mike",
replies Jim. "Are you in Hell??!?" "No, Mike, I'm not in Hell either.
I re-incarnated as a rabbit!"
