This video appears to be from the French Open, although which year remains a mystery to me because, honestly, it's not exactly relevant. What appears to be the central thesis of this video is that Jelena Jankovic changed her underwear right there on the tennis court.
I'll be honest, I'm a little unsettled by this. I'd kind of prefer she did that in the locker room. But I understand that some of you may find this titillating, and to those people I say, "Konichiwa." I hope you find this a suitable replacement until you take a crowded Tokyo subway home just after school lets out.
