There has always been a big divide between parents and children. Even though they love each other, there's a constant clash between them that you just can't stop. I believe it was one of America's greatest philosophers who said, "parents just don't understand." That philosopher was one Will Smith. Or as I call him "Jiggy with it" Christ.
It's true that parents just don't understand, but there's a big asterisk next to that statement. Parents just don't understand *(OK, they do, but they just don't care). If you're going to defeat your enemy, then you must know your enemy. These parent's tactics prove that not only do they understand, but they're ready to outsmart too.
If you're a kid I would suggest that you don't show this to your parents, lest it gives them some ideas. If you're a parent, don't show this to your kids so they don't see what's coming to them. No matter who you are, you'll be surprised by quite a few of these, especially #19.
