I thought that this joke I found on the internet would be perfect for the start of the baseball season.
Two old men had been best friends for years, and they both live to their early 90's, when one of them suddenly falls deathly ill. His friend comes to visit him on his deathbed, and they're reminiscing about their long friendship, when the dying man's friend asks, "Listen, when you die, do me a favor. I want to know if there's baseball in heaven."
The dying man said, "We've been friends for years, this I'll do for you." And then he dies.
A couple days later, his surviving friend is sleeping when he hears his friend's voice. The voice says, "I've got some good news and some bad news. The good news is that there's baseball in heaven."
"What's the bad news?"
"You're pitching on Wednesday."
