My friend Ruffus shot a potato at my head and i'm crying. help?

Well, you see, my friend Ruffus just bought himself the Potato Launcher 5000 and he was giving it a test drive. So, he put a potato inside the contraption and shot one at my bedroom wall just to test it out. He then places another potato inside the contraption and shoots the other side of the bedroom wall, ricochetting to my forehead. I'm crying right now and my mother Betsy checked my head to see if I was alright and I was. How can I stop myself from crying? I've been crying long enough.
