Anyway, George comes up to me the first day of filming and he takes one look at the dress and says, 'You can't wear a bra under that dress.'
So, I say, 'Okay, I'll bite. Why?'
And he says, 'Because... there's no underwear in space.'
I promise you this is true, and he says it with such conviction too! Like he had been to space and looked around and he didn't see any bras or panties or briefs anywhere.
Now, George came to my show when it was in Berkeley. He came backstage and explained why you can't wear your brassiere in other galaxies, and I have a sense you will be going to outer space very soon, so here's why you cannot wear your brassiere, per George. So, what happens is you go to space and you become weightless. So far so good, right? But then your body expands??? But your bra doesn't- so you get strangled by your own bra. Now I think that this would make a fantastic obit- so I tell my younger friends that no matter how I go, I want it reported that I drowned in moonlight, strangled by my own bra.
