Five, six, seven, Aiden, pull down.

One, two, three.

So there's something about the Jane Fonda workout that's never quite made sense to me.

I know I'm inclined to see mysteries everywhere, but I saw one here between the leg warmers and the leotards.

Here's me trying to explain myself during an interview.

That's Fonda at a fundraiser in San Francisco

talking about the importance of gay rights in 1979,

decades ahead of most people.
