I propose we add a further descriptive nuance to Wheetsin's post: IMHO a "yak" is considerably more effort in hurling out the offending mess; it is more that a 'mere PB/sliming' type event, but may contain some of the PB elements. And those little dogs/franks/polish sausages.....somehow they manage to slip past my carefully honed cat like reflexes and turn a delightful lunch into a horrid 20-40 minutes of "full scale PB/yak attack" Careful recent field research on this very matter has clearly demonstrated a Class One Eating Error: failure to chew thoroughly and swallowing too soon. Caught again!....but I have repented and managed to recover quickly. I just don't need those things in my meal plan I guess. *sigh*
