Similar joke:
Cub fan walking on the beach, rubs a lantern, genie pops out and will grant him one wish. The Cub fans ponders for a moment and tells the genie, I'd like to do something that all of mankind could benefit from. Here is a map of the middle east, there is so much war there, I'd like to see peace for all in the region.
The genie thinks for a moment and says, this is beyond what a humble genie can do. They have been at war for generations, it would take the biggest miracle. I can't. How about something else?
Well I've been a Cub fan for a long time and I'd like to see them win a World Series?
The genie thinks for a second and says, "Where's that map again?"
