Well not me, but others yes.
Fun thing to do when dueling Dave was: when the duel starts, start backpedaling like fuck yourself. Dave backpedals too. Keep backpedaling, eventually he'll come after you. He hits you once, then you take a threatening step forward.. and he starts backpedaling again, at which point you backpedal too. It was hilarious and didn't fail to work a single time.
