"Mystery Mug" no mystery to me

[Lillian Dunbar]

This cute mug my parents gave to me when I was 3 or 4 years old (so it's got to be about 55 years old). They put milk in it and set it in front of me so the "surprise" inside was not visible. They made such a fuss and seemed so anxious for me to drink the milk, I became suspicious and refused - (maybe I thought that they were trying to poison me - LOL!). They finally had to pour out the milk and show me what was inside the cup.
