When I came home, the kitchen sink was literally in pieces on the floor.
This wasn't a completely random Tim the Toolman moment. We've had problems with our kitchen faucet leaking, and while I was out running errands sans children, he thought it was the ideal time to take apart the sink and fix the leak, if possible. Turns out we needed a new faucet. Then he checked the Master bathroom faucets, one leaks the other is fine. One came apart without a problem, and he broke the other one, which is why we got new bathroom faucets. This has brought about a full home remodel.
