I do a lot of sitting as a cartoonist. A lot of sitting and thinking. Sitting and thinking and staring and sometimes a little napping. One day after a particularly unproductive writing session that produced nothing but a headache, I was commenting to my wife that I'd mainly just hemmed and hawed all day. And then this cartoon occurred to me, so the day wasn\u2019t a total waste after all. Now if you\u2019ll excuse me, I need to sit and think and stare at the wall again for a while.
