That is kind of you but there is a funny story behind it.

Many others came up with it and it is a known idiom.

But yet I got so confused that I failed to post this solution.

I was about to post, DO NOT LAUGH

sort{ rand <=> rand} (which works BTW)

and eventually there was a thread about the issue and I (not even so kindly)
asked the people to wait for the spoiler period and it was my full intention
to tell them later that
sort_by { rand } was stupid when I found out -in time- that sort {rand} was
stupid and not sort_by{ rand }.

Actually I really do not deserve credit for this one.
