Jack and Joe

Jack and Joe are in a diner where there’s a computer who gives advice to the people in the diner. Jack starts talking about how the two are going to graduate from high school when a young boy walks in. He explains his problem to the computer, which gladly offers him advice. The boy walks out happily.
The computer comes over to Jack and Joe. Joe asks, “Hey, how come you never help us with our problems?”
The computer answers, “I’m just a computer. I’m not a miracle maker.”
