Tweets of the week: Federer's time off, Keys' thoughts on reality TV show

Roger Federer takes his vacation from land to air, Andy Roddick questions his fitness, Victoria Azarenka pulls out a great #tbt and Billie Jean King photobombs a selfie (that means it's probably a pretty great selfie). Here are the best tweets from the week.

Is it really so hard to screw the top back on a container of protein powder @TSA ? Thanks for making my bag look like a crime scene. Again.
