I understand he's posting these around his neighborhood, now, and I mean real Gabe, not the jpeg Gabe like you might see sur le web. If you did find it, I wouldn't bring it back to him. The most likely scenario is that he will assume that you're the one who stole it,
and your "reward" will be a savage karate style maneuver delivered to your "sack of toys."
Someone really did steal his deer, and we explored a kaleidoscope of unique motivations for this depravity. We also discussed a number of scenarios involving this growing collection. My favorite involves a glowing menagerie that swells nightly with each villainous heist, until by some secret signal they march into the forest, still impossibly luminous.
Merry Christmas, you beautiful bastards.
