I read that about a year ago. Yes... it's a joke. If you go back and read it again, you'll notice the names may sound familiar... that's because the person writing the article is "The Dad" on the Brady Bunch.... (not really, but that's the family he used to model the article)
It was written as a joke on a different site than you posted a link to... and it got over 100 messages for feedback at the bottom of the page in less than a day... that many people thought the dude was serious lol... it took a few people pointing out certain things for everyone to realize it was the Brady Bunch. Anyway... thanks for the link... I haven't seen that in a long time, and it's always good for a laugh.
