Rearranging the eggs in the eggbox
I started doing this because mrs fronds takes them from one end, and once you get to just one or two left
O . .
O . .
this can overbalance in your hand quite easily if you're still sleep-dazed and getting them out of the fridge. After actually dropping the box once, I started rearranging them to balance better, eg
. O .
. O .

Now I do it most times I take an egg out, trying to get a reasonably balanced distribution. We've started buying 15-packs now, 3x5, which makes for a lot more potential rearrangements.

It's not something that I get OCD about, I started doing it for practical reasons and now sometimes do it for aesthetics as well, but it doesn't actually bother me if they're not patterned.

Me too!
I try to do it so it's balanced around all possible axes of rotation. Odd numbers of eggs are basically impossible but I reckon the best you can do is:

1:
.O.
. . .

2:
. O .
. O .

3:
O . O
. O .

4:
O . O
O . O

5:
OOO
O . O

Excellent, grasshopper.
You're ready to graduate to 9, 12, or even 15 packs now.
I consider
O . .
. . O
entirely acceptable for when you have just two left. Rotational symmetry is as good as mirror for balancing out the mass.

looks like the i-ching
of egg boxes

But I do this too.
Along with HAVING to check all the eggs in a carton before I buy them

Solitaire
You can try playing Solitaire with the eggs once one is removed, to figure out which one to eat. That one will be thae last one left in the box.

That might even work
with a 12 or 15 grid. Food for thought! (ho ho)

I like the idea of this
and might start buying eggs in larger quantities so I can do it
