Take a look at Top Ten ways to fuck up your kids@Everything2.com. The first version is really funny. What I especially want to try are number ten (pretend to die) and number two (teach them right and left backwards) if I ever have a kid. An Japanese essayist Senoo Kappa[1] (who is also a scenic designer) told a similar story in one of his book: He taught his daughter the usage of "Thank you" and "You're welcome" reversely, then his daughter found that her father was cheating and refused to trust him for a long time. So seriously, if you want to be a good parent, don't try this at home!

[1] It seems that Senoo Kappa is not very famous in the English world. His wiki page only has Japanese version and Chinese version. He's really a funny guy. Even his name is amusing.
