Copilot getting aloof when addressed as "Computer".

Long story short, I've watched too much Star Trek, I pre-face any voice command with "Computer".  Copilot becomes very whimsical and aloof when I do this, any way to instruct the system to be more serious?

The issue started when I made a small joke by stating "Computer, tea, Earl Grey, hot.", it was downhill from there.

Thanks.
