The last time we looked at Lio by Mark Tatulli he was using Mapquest, though it was for purposes of space travel. Now he's using Yahoo Maps. Of course this one is from June of 2006 and the other example was from May of 2007. So maybe Lio switched browsers during that year. The additional joke in this, if you can't see it, is that Lio is getting directions to Washington D.C. for these visitors. Get it?
Why any of them thinks a 2D map is at all useful for space travel is beyond me.
