I'm still sad they removed the Google Maps directions from Boston to London. (At one point, one step was "Swim across the Atlantic Ocean") Now the official answer is 'Sorry, we could not calculate walking directions from "Boston, Massachusetts" to "London, United Kingdom"'
That must have been some sort of a workaround or counterjoke for the actual impossible water crossings Google Maps used to offer. It used to tell me to switch ferries in the middle of the sea!
While this one seems pretty straight forward to add, it's pretty incredible that they have so many great easter eggs. I can totally imagine that a major site like the SERP changing all the time, and maintaining an easter egg can be a helluva bit of tech debt to drag around without increasing profit. Anyways, kudos to that 1 or 2 engineers who convinced a PM to let them have fun for a few sprints.
