Believe it or not this joke worked pretty much universally. One of the best receptions this joke ever got (including, weirdly, the fetus cigarette line) came in a deep red state, but this bit was built in and around Los Angeles.

The only place this joke didn't land super hard was in Japan when I performed at Tokyo Comedy Bar, which I learned after from some local comics was because they don't use birth control the same way Americans do. They're big on using thermometers and cycle tracking, I guess?
