I would never have believed so many posts could be generated by a question of a common name equaling a common name.
This is all great stuff!
My only experience with Osage Orange is up in Davidson, NC, by the college, they have one overhanging the main street and sidewalk. One day my crew was pruning it in the fall, and all the fruit was falling to the ground. Every single person who came up to us asked us if they were edible. We eventually started telling people they were, and that they taste like pumpkin.
Which I am assuming is totally incorrect, but well worth the dissemination of false information.
