Jack Applin sends this in: “A hyphen between “you” and “know”? As in “you-know”? What sense does that make? If she will criticize his punctuation, then she should also condemn the excessive and random number of dots in his ellipses, though she is no better with her five-dot ellipsis.”
So she’s able to read thought balloons clearly enough to discern hyphens?
Is it possible for a comic to be able to be both CIDU & LOL? Because while I have less than no understanding of sailing ship rigging, (… which is likely part of the point of this… and several other … XKCD comics…) the hover text, where I don’t understand “yawl” or “ketch”, still had me LOL-ing: “I wanted to make the world’s fastest yawl, so I made the aft sail bigger, but apparently that means it’s not a yawl anymore! It’s a ketch-22.”
I thought this was a variation of the old joke / soap opera premise in which the mother is shown to have been unfaithful, since 2 + 5 <> 6. But they are laughing in the last panel.
