The Joke

A person asks God whether He is truly all-knowing, all-powerful, and all-good. God confirms, but adds "not at the same time" — He can only focus on one attribute at a time. When He focuses on being all-knowing, He stops being all-good or all-powerful, and things go wrong while He's not looking. The person suggests that God could focus on being all-knowing to look down at an infinitely small time scale, effectively monitoring everything. God considers this but notes He'd then "never touch anything" — He could observe but not act, since exercising power requires shifting focus away from knowledge.

The final panel shows the person sitting alone in darkness, realizing the bleak implication: God exists but is functionally useless, trapped in a divine attention deficit. The small text at the bottom notes this is a "refutation of the Epicurean trilemma" — the famous problem of evil argument that questions how God can be simultaneously omniscient, omnipotent, and omnibenevolent.

The Humor

The comic offers a novel and funny "solution" to one of philosophy's oldest theological puzzles. The traditional Problem of Evil asks: if God is all-knowing, all-powerful, and all-good, why does evil exist? The standard theological responses involve free will, divine mystery, or redefining the terms. Weinersmith's answer is much simpler and more absurd: God has all three qualities, but He can only use one at a time, like a person who can't pat their head and rub their stomach simultaneously.

This reframes the divine being as suffering from a cosmic version of ADHD or single-threaded processing — God is literally unable to multitask. The joke escalates as the person tries to find a workaround and discovers that every solution creates a new limitation. The final dark panel, with the person sitting alone processing this information, sells the existential dread of realizing that God is real but permanently distracted. The "refutation" framing in the caption adds academic humor, presenting this absurd idea as though it were a serious philosophical contribution.
