This was the absolute best episode of Big Bang Theory I have ever seen and probably one of the top sitcom episodes ever irrespective of series. The girls stole the show but I was really astonished at how much Sheldon looked like Brent Spiner in his Data costume (though Leonard's Picard got me to do a double-take as well). The GPS sections were eerie as it was word-for-word a rehashing of Spouse's road trip commentary. The only part that was different was the part where the GPS was hacked so IT was giving the factoids instead of them coming directly from the person who knew them. I have one question: is Stuart gay? I started watching this season and thought that he was based on a few things (included an extended will he/won't he with Raj) but I recently set up our TiVo to catch the syndicated episodes and he was dating Penny in a couple of them, so now I'm not sure what to think. Anyways, his ready agreement that Thor is hot made me think that I wasn't mistaken in my initial impression.
