stop me if you've heard this one

So Jaren passed off pocketknife safety at boy scouts and very thoughtfully approached Cory about getting a knife of his own. Cory took him to Cabela's and picked up this little number. She's pretty cool. I'm told she's a 12 (which is better than an 11?) Anyhow, the next day he told me that he had a paper cut on his finger that he got at school. We were driving and I told him I would take to it when we got home. Later that night with friends and family around I notice that Jaren has taken care of the cut himself. It finally dawns on me and so I ask him, Jaren, don't you think it's weird that you have a cut on your finger and you got your pocketknife yesterday? And he said, No, I got a paper cut at school. To which I said, Scout's honor? His face scrunched up and he knew that he had been caught. He said Oh, man. I hope that he has learned his lesson that his mother knows everything and plus, I have found his kryptonite. <------ Insert evil laughter here.
