What did the suicidal function say?

Q: What did the suicidal function say?

A: "GOODBYE WORLD"

This is another programming joke. This joke relies on the listener knowing that the first program that many people write when they program in any language is to get the computer to print "Hello World!" to the screen.

This is a deconstruction of that practice: having the program say Goodbye World instead of Hello World.

Perhaps some would consider this to be dark humor, but it seems pretty tame to me.
