OK, so I'm at the end of the game (I'm at level 30+) and have discovered 99.9% of the map (just a couple of buildings and vaults i still need to comb over).

Anyways, last night I was just outside Vault 87 (I need to find a radiation suit....anyone have a suggestion?) and while I had just killed a mutant, Dogmeat starts growling, I turn to see what has his attention and in the distance I see a Deathclaw heading my way. So I croutch and get ready to fire away when here he comes and ZOOOOOOOM!

Off he flies into the air, straight up and out of sight. A few seconds later, here comes another one....ZOOOOOM, off he goes.
So I'm thinking, is there some sort of high pressure area that he's walking over? So I head towards that area and Deathclaw after Deathclaw shoots up into the sky and vanishes. So I find nothing but before the next Deathclaw could fly away, I use the VATS and sit back to see what happens. I get one shot on him before he flies away and then as the second shot is about to hit and kill him, the camera angle changes to show it in third person view as his guts splatter and I could see me, way down on the ground below.....it was the funniest damn thing I ever saw in this game!

I wish there was a way that I could record this happening (I'm on a PS3) and post it here. I set a marker so I could go back and see it happen again and again.
