a-pump
Explanation
The Joke
A woman tells her partner she bought a plus pump. Her partner says she will be just fine. She clarifies: "Not that kind of pump -- it is an energy storage system." She explains that the energy from each thrust into the pump is used to elevate water, and later, when they require electricity, the water is passed over a series of turbines. Her partner realizes this means the entire household operates by the grace of her anger. The final panel delivers the punchline: the reason her partner has not been interested in her for six months is because she wants to run the air conditioning all summer long -- implying she needs her partner to make her angry to generate enough pump energy to power the household.
The Humor
The comic takes the real engineering concept of pumped-storage hydroelectricity -- where water is pumped uphill to store energy and then released through turbines to generate electricity -- and applies it to a domestic relationship in the most dysfunctional way possible. The "pump" is powered by angry thrusting (presumably stomping or some physical expression of frustration), meaning the household literally runs on one partner's rage. The relationship has been deliberately neglected not out of apathy but as an energy policy: the more frustrated and angry she is, the more she pumps, and the more electricity the home generates. It is a darkly funny metaphor for a relationship where conflict is not just tolerated but actively cultivated for practical purposes.

- Pumped-storage hydroelectricity is a real and widely used method of energy storage. During periods of low demand, excess electricity is used to pump water to an elevated reservoir. When demand increases, the water is released through turbines to generate electricity. It is one of the most efficient large-scale energy storage technologies available.
