Some background on this comic:

Transcript of relevant bits:

In my first year or so of drawing The Far Side, I was scared to death of making mistakes in the artwork. Incredibly, I had never heard of a product called "White Out" (for covering up mistakes) and the smallest screw-up meant starting over. So, as I've indicated under each of these cartoons, I sometimes left things out

The fellow coming through the door is incompletely drawn because I feared the lines of his body would interfere with the auditioner's head. Obviously, I choked.

That's actually quite impressive to miss by THAT much!

Reminds me of the old, politically incorrect, joke about people in some kind of institution for those with intellectual disabilities and poor coordination.

At a group session, the doctor tries to get each patient to clap three times in a row. A few try, and end up like the guy in the comic here. One manages a single clap.

Then one manages, with great effort, to do three in a row.

... and then everyone present gives them a round of applause.

(If this seems relatively tame, it was usually acted out with imitations of the people... yyyeeeah. We don't do that any more.)
