I actually have the entire series of Invader Zim on DVD, the collector's edition house box set. Y'know what's crazy? A couple months ago I looked up how much it's worth. There are listings on both Amazon and ebay for anywhere from 250-500 dollars, depending on whether the Gir toy is still with the set or not. I've thought about selling the set and just buying the DVD's again, but I don't know for sure if I want to do it or not.
