Boy, this whole Gecko story just got more interesting. My dad informed me of a few things...
First, it seems that while all this "rectal inversion" was going on with Fez, the little guy somehow managed to INSEMINATE Art (whom we now know is female). Yes, Art laid an egg. Now, one must ask the question, "Did Fez injure himself during this act of procreation during a state of frenzied orgasm?? Seems likely, but then according to Wikipedia some geckos are parthenogenic, the females capable of reproducing without copulating with a male. According to the article, this improves the geckos' ability to spread to new islands. The gecko version of suburban sprawl.
The news today gets even more scientific. Apparently, you can control the sex of a newborn gecko by altering the temperature at which the egg is kept. If you raise the temperature you can bring about hatching in just four weeks and insure that the newborn will be a girl. If you lower the temperature, you get hatching in 16 weeks and insure getting a boy. I believe if you lower the tempurature past 64 degrees the gecko is born as a crochety old Jewish man with an enlarged prostate.

Oh, the decisions one must make in child rearing. See, look at that. I took a topic that had nothing to do with the overall subject of my blog and turned it into one that did.
