RE: They can't stop laughing
Make them think you're as nutty as possible. Joke's on them.
Tell 'em that you've never killed a deer before, then they won't pester you about taking them to one of your honey holes.
Tell them that you can "taste" the deer with scent glands on your tongue, like a snake, and you're hoping that you can finally capitalize this season.
It's always more fun when people think you're totally insane, then they never know when to believe you, even when you tell the truth. Keep 'em guessin'.
