A couple made a deal that whoever died first would come back and inform the other of the after life.

The woman's biggest fear was that there was no heaven. After a long life the husband was the first to go and true to his word he made contact.

"Mary... Mary.... "
"Is that you Fred?"
"Yes, I have come back like we agreed."
"What is it like?"
"Well, I get up in the morning, I have sex, I have breakfast, I have sex, I bathe in the sun, then I have sex-twice, I have lunch, then sex pretty much all afternoon-supper-then sex till late at night, sleep then start all over again."
"Oh Fred you surely must be in heaven."
"Actually no, I'm a rabbit in Kansas."
