Mine was when the party:
1.) Crippled a Bad Ass Zobie Knight through stunts and hindering cuts so that he could barely move.
2.) Set him on fire.
3.) Endured a counter-attack from the BAZK where he fought back by staying on top of his tomb where he had higher ground, intimidating them through unearthly howling, and throwing burning chunks of himself at the PCs.
4.) Fixed themselves in seconds after a deadly fight by using their reserves. No more arguing about healing spells. Just, "Oh God, oh God, we're gonna die," followed by, "Hey, we didn't! Yea!"
I don't think I can ever go back to stuntless combat.
