My mom...in her 60s folks call us "Mr. and Mrs. Gallium".
My wife...I took my wife to the OBYGN when she got knocked up, we are there with the rest of the boys, the eldest was a recent teenager. The nurse comes out, looks at us (4-5 of us), and then begins addressing my wife and teenager as Mr./Mrs. Gallium.
Funny thing is, when I shave and wear "young people clothes" (jeans or cargo pants/etc), people think I am no older than 30.
