My last name is McDonald.
I had a nickname, which I wore proudly, during my corporate career as Ming the Merciless
I had also credited my Celtic background for this.
When I lived in Germany, I used to visit the many Celt burian grounds. Huge mounds of earth.
When Jesse Jackson came to West Palm Beach, FL during the contested election, I frequently had visions of his head tied to my belt.
I settled on using my bullhorn due to my meek, retiring and tolerant nature :)
