An old one but good:
Two old guys, Abe and Sol, are sitting on a park bench feeding pigeons and talking about baseball, like they do every day. Abe turns to Sol and says: “Do you think there’s baseball in heaven?”
Sol thinks about it for a minute and replies: “I don’t know. But let’s make a deal – if I die first, I’ll come back and tell you if there’s baseball in heaven, and if you die first, you do the same.”
They shake on it and sadly, a few months later, poor Abe passes on.
One day soon afterward, Sol is sitting there feeding the pigeons by himself when he hears a voice whisper: “Sol… Sol…”
Sol responds: “Abe! Is that you?”
“Yes it is, Sol,” whispers Abe’s ghost.
Sol, still amazed, asks: “So, is there baseball in heaven?”
“Well,” says Abe, “I’ve got good news and bad news.”
“Give me the good news first,” says Sol.
Abe says: “Well, there is baseball in heaven.”
Sol says: “That’s great! What news could be bad enough to ruin that!?”
Abe replies: “You’re pitching on Friday.”
