Teacher's wooden ruler

Here's the thing, teachers liked to use wooden ruler to punish the bad boys back then when I was still in elementary, junior and senior high school.

And I was once spanked by a crazy math teacher for didn't pay attention when he's teaching on a hot day.
Bad bad Leroy...

It broke into 2 pieces after that, so imagine how bad he was.
(Hmm its material was kinda soft and light like one used for beer's box, so it could break when use to spank so hard)

But the one I got now is made from a very hard wood, so it sure won't break.
And if one uses it to spank, hell, it hurts whole lot.
