Thank you, ofnimira!

Fun to use this as a "what thinking-process do you use" test...!

I just told this to my husband, who had just woken up, and it took him a second to get it. A second, whereas I, wide-awake and furiously trying to think with linear logic - always a stretch for me - wrestled with it for ten minutes and still didn't get it. Oddly, now that I get it after your explanation, I think it's absolutely hilarious, whereas my spouse is still waiting for the punch line.
