What I found funny was that the cane suddenly turned into a paddle with holes.
I misguided some of you and I apologize. It wasn't a cane at all. It was a ruler. She's holding a ruler as she stands in front of the blackboard saying, "I'm sick and tired of your excuses, give me an answer." As for the cracking sound, if you have On Demand and can see Season 4 Episode 7 over again, (it will show up as 407) listen to when Nathan sits up quickly on the couch when waking up. You can hear the cracking sound along with the burst of music. In the trailer it cuts off before he sits up.
Yeah, it was a bit of a letdown as far as the paddling, but it was totally erotic, too. I can only imagine having to stand up totally naked in front of a teacher looking like she did.
