I'll never forget when I was a kid an my brother was trying to convince my dad that he could smash a beer can on his forehead.  We all died laughing as he failed and ended up with a big red ring on his head and a bruised pride.  I would think that a watermelon would be easier than that.

Evidently, it's not.

He's 10 years old and he thought that because he took Tae Kwondo, he could take on the watermelon and win.  And he was wrong.
