One of the traditions here on Mars is sharing the weird and wonderful postcards that arrive in my mailbox, but it’s a tradition that hasn’t got nearly enough love in the past two years. Friends, family, and clients have sent me a joyous pile of fun, thoughtful postcards since I relocated to Tucson in early 2021. They are always a bright spot in my day, and they get displayed in the Martian HQ for months before being filed in my archives. Maybe before I blow out of this hellhole in Tucson forever in three weeks to start the next chapter of my life, we’ll enjoy a postcard retrospective.
Before we get to all that, I want to share one that arrived this week, because you might have some insight into the question it poses. This postcard is the very first to arrive completely unsigned since the hilarious call to begin the intergalactic invasion in 2013. Sending random unsigned postcards to make someone’s day a little more surreal is exactly the kind of frivolity this blog was founded on more than a decade ago.
I still don’t know for sure who sent the invasion postcard, but I am pretty sure I know who sent the following robot riddle for me to solve. I thought you might like to take a shot at solving this riddle, too. Post your answers in the comments, and maybe you will help the mysterious sender get some ideas for her robot novel.
What is the sound of an inert robot when he’s laughing?
I came up with one solution to this riddle based on a post at https://www.livescience.com/electricity-humming-noise, but you might have ideas of your own. And if you have never received a postcard from me personally, then that’s on you! Email me your address and get on my list for mailings that go out at irregular intervals once or twice a year.
