Ugg boots with shorts?

There was a Facebook group called Uggs + Shorts = Epic Fail, but it only comes up for me in Google and not from within Facebook. Maybe I'm looking for it wrong; I still can't get the hang of Facebook's so-called user-interface.

Personally, I wouldn't go as far as to call it an epic fail, but it leads me to suspect that some of these are the women who only own flip-flops and Ugg boots. Maybe they wanted a break from flip-flops that day.
