From the original Getter Robo anime (Getter Robo is known for having the first ever combining robot, even though it actually didn't), which I've heard is rather tamer than its counterpart manga, we have this:
Yes, that guy just killed a snake by throwing his harmonica at it. And after a quick wash in a nearby body of water, he's willing to play it again.
Of course, the same guy also beat a dude to death with a soccer ball...
Wait, this was tamer than the manga?
(Considering what I've heard about the manga, yes it was.)
