Ehem
Give that sock hair everywhere except on its head and you've got Sampras.
Also, some people like Tarantino (who looks like an evil Federer) are into feet. So for them, Jack Sock sounds more like an invitation or a type of sock than a person's name...
Hopefully he pulls of a Mardy Fish and loses weight. I'm just hoping that Sock does so far sooner than Fish did, who left it way too late.
And on a side note, it's somewhat unfair that we can talk about Sock's weight so openly, yet the moment you make a similar comment about Taylor Townsend, suddenly it's hateful and bigoted.
