This past week included one of those odd days that’s so busy I get a column’s worth of topics from a single day’s reading. And there was another strip (the **Cow and Boy** rerun) which I might have roped in had the rest of the week been dead. The **Motley** rerun might have made the cut too, for a reference to .

Jason Chatfield’s **Ginger Meggs** for the 5th is a joke about resisting the story problem. I’m surprised by the particulars of this question. Turning an arithmetic problem into counts of some number of particular things is common enough and has a respectable history. But slices of broccoli quiche? I’m distracted by the choice, and I like quiche. It’s a weird thing for a kid to have, and a weird amount for anybody to have.

JC Duffy’s **Lug Nuts** for the 5th uses mathematics as a shorthand for intelligence. And it particularly uses π as shorthand for mathematics. There’s a lot of compressed concepts put into this. I shouldn’t be surprised if it’s rerun come mid-March.

Tom Toles’s **Randolph Itch, 2 am** for the 5th I’ve highlighted before. It’s the pie chart joke. It will never stop amusing me, but I suppose I should take **Randolph Itch, 2 am** out of my rotation of comics I read to include here.

Zach Weinersmith’s **Saturday Morning Breakfast Cereal** for the 5th is a logic puzzle joke. And a set theory joke. Dad is trying to argue he can’t be surprised by his gift because it’ll belong to one of two sets of things. And he receives nothing. This ought to defy his expectations, if we think of “nothing” as being “the empty set”. The empty set is an indispensable part of set theory. It’s a set that has no elements, has nothing in it. Then suppose we talk about what it means for one set to be contained in another. Take what seems like an uncontroversial definition: set A is contained in set B if there’s nothing in A which is not also in B. Then the empty set is contained inside every set. So Dad, having supposed that he can’t be surprised, since he’d receive either something that is “socks” or something that is “not-socks”, does get surprised. He gets the one thing that is both “socks” and “not-socks” simultaneously.

I hate to pull this move a third time in one week (see here and here), but the logic of the joke doesn’t work for me. I’ll go along with “nothing” as being “the empty set” for these purposes. And I’ll accept that “nothing” is definitely “not-socks”. But to say that “nothing” is also “socks” is … weird, unless you are putting it in the language of set theory. I think the joke would be saved if it were more clearly established that Dad should be expecting some definite thing, so that no-thing would defy all expectations.

“Nothing” is a difficult subject to treat logically. I have been exposed a bit to the thinking of professional philosophers on the subject. Not enough that I feel I could say something non-stupid about the subject. But enough to say that yeah, they’re right, we have a really hard time describing “nothing”. The null set is better behaved. I suppose that’s because logicians have been able to tame it and give it some clearly defined properties.

Mike Shiell’s **The Wandering Melon** for the 5th felt like a rerun to me. It wasn’t. But Shiell did do a variation on this joke in August. Both are built on the same whimsy of probability. It’s unlikely one will win a lottery. It’s unlikely one will die in a particular and bizarre way. What are the odds someone would have both things happen to them?

This and every Reading the Comics post should be at this link. Essays that include **Ginger Meggs** are at this link. Essays in which I discuss **Lug Nuts** are at this link. Essays mentioning **Randolph Itch, 2 am,** should be at this link. The many essays with a mention of **Saturday Morning Breakfast Cereal** are at this link. And essays where I’m inspired by something in **The Wandering Melon** should be at this link. And, what the heck, when I really discuss **Cow and Boy** it’s at this link. Real discussions of **Motley** are at this link. And my Fall 2018 Mathematics A-To-Z averages two new posts a week, now and through December. Thanks again for reading.

The Mike Shell retread isn’t so funny, but if it got to be a running gag, that could be good.

Yeah; I didn’t think anything of the strip until I realized it was a running joke. Actually I thought it was a repeat, and only realized it wasn’t when I checked my archive. I don’t know where you can go after being struck by lightning and eaten by a crocodile-or-alligator.

The humor-writer side of me likes that if this is a running gag they’re not giving it away. Like, not by doing a lottery-winner joke every Monday for a month, or making some reference to a previous strip, or anything. Just leaving it for people who happen to remember particular panels of one strip out of two hundred. It’s got a certain audacity to it.
