Different Kind of Similar

AC/DC, doing a math problem: I know how to solve this. But I’m going to solve it the right way. You know, like a real man does.

“Is my car making that knocking sound?” I asked Good Man. Several months ago my car was making a knocking sound. Something was missing and had to be replaced. It’s been making a much quieter creaking sound very recently.

“Different kind of similar.”

“‘Different, kind of similar?’ Or ‘different kind of, similar?'” I teased.

“No, dash dash dash.”

“Different—kind of similar?”

“No!” Good Man cried, “Different-kind-of-similar. A compound!”
