Mechanical mishap stories

So the boat I work on had a leak in one of our water cooled exhaust manifolds, the turbine blades didn’t react well to the coolant.

Tried to wire a high beam warning light into a Citroen 2CV. Wire chafed through when re-attaching the dashboard plate. The dashboard wiring on a 2CV isn’t really fused. Much smoke and replacing of wiring loom bits followed.
