Why can't you just break it? Then you don't have to try to suck out the meat between the two bones and you now have a weapon on hand if someone tries to grab one of your wings.
Tuq, wrt to the flats comment I made, that's just been my experience - you grab a flat, have to use two hands, have to bite on both sides and there's still meat that's awkward to eat. Consequently, I usually just have to push it out with my finger or something. I don't know, seems like more work than eating the drum, but that's just my opinion.
Grab the thinner bone and twist or put your fork through the middle and twist.
Yeah the move with the flat is to break it, unless you know how to do that other move where you cleanly remove the bones and eat the whole thing, which I don't.
If weaponry is need while eating, I don't even, I mean what the hell kind of dining experience are you having here?
