Harrington & Richardson single shot 20 gauge. Got it as a birthday present when I was 11 or 12; purchased at a Holiday Station Store back in Michigan <mumble> years ago. My dad still uses it, and a shepherd mix dog, to keep the varmints away from his chickens. Haven't had the heart to ask for it back.
Mossberg 500 .410. Birthday present from my Grandpa He bought it new way back when they first came out but never even put it together so years and years later I got it in pristine condition in the box.
