Today was 11/12/13, a fun date for those people who like to enjoy fun dates.¹ The date has compelled me to post something with a numerical theme, though not about those particular numbers.
A few months ago, we were telling jokes in the car on our way somewhere or other. I don’t recall who started telling jokes, but at one point the conversation went something like this:
John: Why 7 is afraid of 8?
Phoebe: Because 7 8 9!
Theo: Why is 3 afraid of 4?
Everyone else: Um, we don’t know. Why?
Theo: Because 4 is REALLY REALLY MEAN!
Can’t top that.
And just because, here are a few photos of numbers.
Some numbers written by Theo at age 3. Perhaps they are all facing the wrong way out of fear of the number 4.
Who knows what sinister plans the 4 has for the 5 here?
Two 4s, looking as menacing as you might expect.
¹Yes, I am one of those people: Cf. my many Pi Day posts, as well as posts for 12/12/12, 11/11/11, 10/10/10 etc. Hell, I even posted something on 7/8/9 that I’d completely forgotten about.

As the resident mathematician, I approve! :)
I’m in for any and all number posts. And my 1st graders tell me the 7-8-9 joke endlessly.
I love this post so much.
