The second video doesn't make the first a fake. I'm no scientist, but there are waaaayyy to many variables involved to reach any general conclusions about either video. Now if the same guy could ask out 100 women to get a good sample size, then erase their memories and do it again with the fancy car (same guy, same women), perhaps. The first one at least was funny.
I have thus concluded that women who are gold diggers will react like the first video and those that aren't, wont!
