Let me guess - he's an 'old' guy, right? And I don't mean age, but taught 'old school' ways, because people weren't very educated back then and this was the simplest way to get them to understand that things work, but not necessarily how.
"The lead has to be hot to get through a duck's feathers."
"If you smoke your pipe after shooting a deer, you'll kill it faster."
"The old pointy army bullets aren't good for hunting because they pass through the deer too fast."
And so on, and so forth. I know guys like that, too, and you can't argue with them.
