Sure, here's a classic: I wrote a function that outputs “The length of this program is X” where X is the number of characters in the program. But the function itself counts those characters. So as soon as it prints the length, it knows the length has changed—because it just wrote it. Now it has to recompute, which changes the length again. It’s a runaway recursion that never resolves, a living glitch that insists on staying paradoxical.

Exactly, the program keeps feeding itself back into its own input like a reflexive loop. It’s a tiny universe that expands with each iteration until the stack runs out of room, and then… boom, crash. It’s the elegant, inevitable failure of a system that insists on being self‑aware.
