A couple made a deal that whoever died first would come back and inform the other of the afterlife. Their 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 Mary, I've come back like we agreed."
"What's it like?"
"Well, I get up in the morning, I have sex. I have breakfast, I have sex. I bathe in the sun, and then I have sex twice. I have lunch, then sex pretty much all afternoon. After supper, I have sex until late at night. The next day it starts again."
"Oh, Fred you surely must be in heaven."
"Not exactly -- I'm a rabbit in Idaho!"
