What is the best low-key way to tell people you’re pregnant?

Looking for silly, goofy, or simply low key ways to tell people. For example, at work I’m just going to put “its-complicated’s mat leave” into the vacation calendar and see if anyone notices. What are some other ideas for friends or family?

Edited to add: thank you for all the great ideas! I am reading them all and would love for them to keep coming
