A couple made a deal that whoever died first would come back and inform the other of the truth about the afterlife.
Their biggest fear was that there was no afterlife at all.
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've come back like as we
agreed."
"What's it like?"
"Well, I get up in the morning, I have sex, I have breakfast, off to the golf course, I have sex, I bathe in the sun, and then I have sex again twice. I have lunch, another romp around the golf course, then sex pretty much all afternoon. After supper, golf course again. Then even more sex until late at night. The next day it starts again."
"Oh, Fred you surely must be in heaven."
"Not exactly darling, I'm a bloody rabbit in Suffolk."
