Where does the phrase "Sit down, you're making me nervous" come from?

Throughout my life, my father has often said “Sit down, you’re making me nervous.” At the moment I’m watching Humphrey Bogart in The Big Sleep and he just said that (about 84 mins in) in the same fashion. That got me thinking, “where does this expression come from?”

After reading a few internet posts, I’ve discovered that it was also used in the 1993 film Benny and Joon, and also that this is a semi-common saying, at least in the Mid-West. Both of those facts point to the idea that this could have originated with Bogart (or one of the four writers responsible). My father has probably seen the film, but would most likely not remember whether or not he picked the line up there.

Have you used/heard this? Do you have a usage prior to 1946 or some other idea about it’s inception?
