Need help with Names that describe your profession

I'm writing a skit for work for my kids about the medical field and I'm trying to come up with some names for their characters.

I want something that will be clever like

Juanita Doctor (ie. I need a doctor.)

There will be families (one's last name will definitely be doctor, and the other one, I'm not sure, maybe a body part like Heart or something?)

Thanks in advance!
