I was going to write a post about Baryshnikov’s homotopy-theoretic proof of Arrow’s theorem — and I will! Because it is cool! — but it’s gotten very late, so instead here’s a nerdy joke I heard on Marc Maron’s podcast.
Guy walks into a bar, says “Gimme a martinus.”
Bartender says, “You mean martini?”
Guy says, “If I wanted two, I would have ordered two!”
I highly recommend Maron’s podcast, by the way, as long as you’re interested in hearing stand-up comics talk about their anguish, the terrible mistakes they’ve made, and the weird alcoves and deformations of their inner lives. Also, there are jokes.
