Stupidest Puzzler ever. Not because of the problem itself, but the behavior of the two people. The Character Played by Dan (CPBD) walks two miles down and back to get a crowbar when the neighbor has a perfectly good Jeep right there, in the hope that he might git him some free firewood. And he forgets the most important word in the English language: “why?” Okay, maybe “how” or “please” but this was a job for “why?” Remember, the neighbor could have driven the Jeep back to get the crowbar. He hadn’t even found the right spot for the Jeep yet. Even though he had done this before.
Why is the neighbor the banjo player from Deliverance? He lives in the country where his barn and his woodshed are a mile apart and he doesn’t have jumper cables or a jack in his Jeep.
The solution is a CarTalk trope.
What, you haven’t figured it out yet?
