Whenever I'm talking about mask wearing by people alone in their car or outside going about their business, I always say to people "yeah, imagine wearing a condom and then going to bed alone!". Usually elicits a laugh, but unfortunately I still don't think it goes through to peoples' heads the absurdity of it all.

I should start telling people that they're swabbing peoples' butts for COVID now and the best way to stop spreading the virus is to wear 10 pairs of underwear so the farticles can't seep through. :)
