Innovation

The phrase "jury rig" or jerry built, or jerry rig has several possible origins, the one I'm most familiar with derives from the waning days of WWII when the Germans, or "Jerries" had to improvise a lot of their equipment, and afterword, their whole economy.

Here's a site where improvised solutions, for better or worse, are celebrated. Duct tape, hose clamps, and what-have-you are quite popular.
Of course if this guy could learn to drink more pedestrian scotch, maybe he could afford a proper overflow tank for his radiator. OTOH, you have to keep your priorities straight. To ruin a good quote: Good Scotch will get you through times of leaky radiators better than a leaky radiator will get you through times of no Scotch.
