Kill Zero Process Check

You can kill(0) to check if a process is alive Like pointing a gun at a body to see if it twitches.

A programming joke compares sending the harmless kill(0) signal to a process with pointing a gun at a body to see whether it twitches. The punchline humorously frames a technical liveness check as a disturbing test on a corpse, so it works as a reaction to morbid or darkly technical situations.
