Kids aren't supposed to be able to think everything through clearly, right? They're just kids. So, it's hard to know whether to be angry or gleeful about this not-quite-all-that-clever prank. Watch this kid jump off his bike, approach the front door (being monitored by a camera), stare at the camera, and then proceed to lick the camera lens before ringing the doorbell and running off. Unless this was a prank where he wanted everyone to know it was him, this is a pretty good example of the whole "not well thought-out" concept discussed earlier. Major points for the camera licking though.
