Those things guys do...
Apparently guys do things without knowing it that are quite sexy to potential partners
In this day and age, you never can tell what is sexy or not. It seems to vary from movie to movie.
For example there was the whole Adam Sandler mess up but its cute faze, then the whole surfer chilled out Owen Wilson vibe and then Hugh Jackman forced us all to hit the gym with his sauve Wolverine style.
Then this video appeared and hope was restored.
If you aren't doing at least one of these things - get to it!
