What did Hank Kimball accuse Mr. Douglas of doing?

"Never start talking unless your voice comes out" which is Season 2 Episode 22

In the episode, Mr. Douglas gets an offer to go to Washington DC but the whole community tries to give him law work to stay.

When he does decide to stay, Mr. Haney can't figure out why, because he only made a little over $16 the previous year farming.

With all Lisa's jewels, his car, and fancy clothes, they conspire he must be doing something else besides farming.

Hank Kimball goes to visit Mr. Douglas and says that they are on to him.

The first thing he accuses him of is counterfeiting and asks where his printing press is.

This is where I got lost.

I'm watching this on Antennae TV or MeTV or one of those rerun channels.

It must have been something not politically correct these days, because they muted Hank's voice. I thought the sound just dropped off, but he said it at least one more time, and it happened again.

Does anyone know what Hank is accusing Mr. Douglas of?? I tried to find a script online with no luck.

Thanks in advance....
