HA! that is sort of cool having a parent teach their kid a 2nd language, but why klingon, so he can be like to his friends hey look at what my kid can do. I love star trek so i aint knocking it, but parenting is a huge responsibility and he shouldn't have done it imo but people are stupid. Thanks for the list, the rest of them gave me a good laugh.
