What do you consider the most difficult food to eat?
I can't say that I've run across anything all that difficult to eat - you put it in your mouth and chew, aye?
I suppose some food is more sloppy than others. Some foods make it tougher to get to the good parts, too. But 'tis just a challenge worth undertaking!
I've never run across a food that's gotten the best of me, however! Well, okay, going-down-wise. Coming back up is a different topic all together.
