Mathematics cartoon: help in finding it? (Easy verbal description.)

Factual Questions
1

I recall this cartoon often:

Two men standing in front of huge blackboard.

Long string of mathematics symbols; kind of spiky bubble, like “burst” indicator in comics, and written in the bubble “Then a Miracle Occurs”; another string of mathematics symbols; ending with equal sin and a string of symbols.

One guy, with a pointer to the “Then a Miracle…” says “I think your problem is right here.”

Could be New Yorker from years back. Before I find out if they even have a usable index, I was wonder if anyone could nail it.

What do you need? The cartoon, which is the first choice when you google image “then a miracle occurs”?
Google has this nifty new option called “images” which actually works almost as well as SDMB.

The signature “S. Harris” quite legible on it?

The picture (obvious ripoff) of a pair of bugs and the algorithm flowchart with “then a miracle occurs” and caption “this needs a little work” which I’m sure I saw in a computer trade magazine add too…?

It’s well-known enough, so just googling ‘then a miracle occurs’ brings up (among others) this flickr, which also lists the origin as The American Scientist, 1977, by one Sidney Harris.

The middle bit of any plan is often the tricky part.

That’s the same cartoon. And it’s not the Far Side. It’s even signed S. Harris.
