I gotta say though, turning on caps lock does seem to get them to cut out the inane banter.

There are other methods, including asking them to eg speak using the Google style guide rules, or to speak at 2/10 verbosity, or to speak as if they're talking to a very intelligent middle schooler, or to use simple sentences in subject verb object form
