There should have been some analysis of from what height one would be able to jump into a pool of water. With 16% of earth's gravity, 30 meters on the moon should be like 5 meters on earth. And people jump from 30 meters on earth, so those people should be able to jump from 190 meters on the moon. Maybe even higher if you account for the lower terminal velocity!
If you don't know about XKCD mouse-overs, you've been missing half the joke on every comic he's ever done...I've been reading "what if"'s for a while now, and I literally just realized that if you hover your mouse over an image, there's more text. Some of them are good. Like, there's an image of two cars in orbit above Earth that says "How did you get up here?" "Tesla Software Update. Elon Musk clicked on a SpaceX file by mistake.", but then if you hover your mouse over the image it says "He says they're rolling out a fix which will let us all reenter the atmosphere and land safely on his barge, but no one wants to be the first to try it."
I think I might be going to back to mouse-hover other "what if"'s now.

I know and love the XKCD mouse-overs, but like JRod I did not know there was text for the "What If?" illustrations as well. I am about to waste the next hour going back and viewing ALL of these
