Can I speak to your mother?
My family practice is an office with two GP for adults, 3 peds and one pediatric Nurse Practioner. The pediatrics is probably one of the bigger groups in the small suburb they are located, there are rarely many adults without kids in there.
This morning my cell phone rang "May I please speak to the mother or father of Amanda _____?" I recognized the number and started laughing "Well, I am 27 and thought I was an adult but you can have my mom's number if you need to speak to her." The nurse then started laughing and admitted she makes most of her calls for the pediatrics side. 
It was a fun little chuckle to start my busy and a bit stressful morning.
