There is a right and wrong way.
Yes, I know several ways to do it. As kids, and still sometimes now, I simply roll the orange on the counter to soften it, then cut a funnel shaped hole at the end where it was connected to the tree. Then I squeeze the orange and drink the juice right from the orange until I can't get any more juice out of it. I then split it open and eat the meat. That is how we did it as kids all the time. I think it was mother's favorite way since she didn't have to cut them up and not a drop of sticky OJ hit the floor.
With your toenails.
a wrong way
is with a potato peeler
Oh no, that would never work. :)
