Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This comic depicts a schoolyard bullying scenario with a computer science twist. A bully grabs a smaller kid and demands, "Gimme all your lunch money!" The victim replies, "I have money, but it's for a field trip, not lunch!" The bully then says, "Next time, before you come to school, designate your money for lunch!" The caption reads, "It was nice being at a computer science prep school."

The humor is based on how literally and precisely the bully interprets the concept of "lunch money." In a normal bullying scenario, "lunch money" is just a generic term for any cash a kid has. But at a computer science prep school, even the bully thinks like a programmer -- he treats "lunch money" as a specific variable type and insists the victim properly allocate and label his funds before bringing them to school, much like a programmer would designate memory or type variables in code.

The votey panel simply states, "Computer scientists are very literal," reinforcing the joke that the pedantic, precise thinking characteristic of computer science has infected every aspect of life at this school, even bullying.
