Growing up in Arkansas we saw these all the time. It sure looks like what we would call "Horse’s Apple" never ate one. And I still don’t know what it is. But when I saw the picture it triggered a Flash Back and the name popped in my mind without hesitation. I know as kids,this was our Hand Gernades when we played Army and yes they hurt like Hell when you get hit by one. But they were fun to throw.
Thanks for triggering a long lost moment of my youth. Too Funny….
