Think back when you were a kid.  Did you ever fib to your parents?  C'mon, tell the truth!  We all did it. Ralphie did it when he told his mom that an icicle fell and hit him in the eye instead of a ricochet from his new bb-gun.  Why do they do it?  The answer is quite's so much better than the alternative of being in trouble.  Right?  Kids think for right now, they don't think about consequences of their actions later.  Take a look at the kid in this video.  He is caught practically red-handed, yet continues to string his mother along.  Enjoy!
