Out Of Context Star Trek Moment: Jazz Hands?

Wow, it's been years since I've posted one of these, so it's high time I remedied that.

I've been an avid Star Trek fan for many decades. I've seen every episode countless times, I've got tons of reference and behind-the-scenes books, action figures, model ships, trading cards-- you name it, I've got it. With that said, even I have to admit that certain episodes could get a little silly now and then, especially when viewed out of context.

So sit back and enjoy this totally Out Of Context Star Trek Moment.

Is this Guinan's failed attempt at performing "jazz hands?" Or was this from that time she auditioned for Dr. Crusher's shipboard production of Cats?
