You want an explanation Mr. Cash In? Well you've got yourself one.
In my years, I've seen some things, and one of the things I've seen is what geese will do when they are mad. I've seen geese attack and greatly hurt fellow ponies. And Cursing Goose had the capabilities of inflicting such harm, especially if it can swear so powerfully that one can receive pain. And I don't believe I ever said what kind of blows to the head my client received. For all we know, they could've been mental blows powerful enough to cause brain damage.
