Is it possible to sprain both ankles in a single fall?

Yes, yes it is.

I had a really unlucky fall while bouldering last night.  C thinks that since I went through the first 25 years of my life without a single injury, I am merely making up for lost time.

Getting carried around everywhere (and I do mean everywhere) and having everything served to me whilst I lie in bed has been great (for the first 5 minutes) don't get me wrong, but by 3:30PM today I was googling how long it will take before I can escort myself to the bathroom.

Funny thing is, not many people sprain both ankles in a single fall...in fact I found a thread asking whether or not it was even possible to do so.  There was only one answer posted:

Not unless you are Chuck Norris.
