Naturally, because the skid marks are harder to see.
As for opening lines...Dunno, I typically don't go out to such social settings. Even if I did, I'd quickly retreat into myself, and end up sitting in the corner, watching everyone else enjoy themselves. (Yes, even at parties like the one earlier this year). But it's not like any ladies would be sending me "come hither" glances. (Before some one comments on that. This is deeply held 'belief' that yes causing me great difficulty to even shift)
But I do agree with Rebecca, IMO KISS is best. But again I have no personal proof of that
