I was confused at first

I thought all 6 was 1 joke, like the standard 1 joke per comic, right?

Then I saw the Stones, and thought the cadence was … 3 rows 3 jokes and the background colors are green (first row), grey (second row), and then … no I’m overthinking this

Then I saw Zeppelin in the 3rd row.

Oh, it’s 6 jokes!!!

Eventually I got all the jokes. So that’s my accomplishment for the day.
