Note that the timing is everything here. You need to yell out your Moo before the other person finishes the Interrupting cow who? portion of the joke, thereby interrupting them. Trust me, it's hilarious! If you spend time with younger kids or with adults who need to lighten up (and who doesn't?!?), try this out on them and see for yourself."
Basically it is about AI interrupting you, and just in the right momment too. Super hard to do from a technical perspective.
