Willing to pay an arm and a leg for those World Series tickets? Then you're willing to give up two of your limbs for the season's biggest baseball games.
Arms, legs, wings, flippers — these are all examples of limbs. But we shouldn't leave out the trees. They've got plenty of large branches or limbs as well. In fact, when you expose yourself to potentially negative consequences in order to help someone else, it's called "going out on a limb" — like crawling out on a big tree branch. Not a flipper.
