I was first licensed as a Technician class back in 1977 with a station call sign (note that no person can have a call sign, only a station can) of WB7WHD. It was a mouthful.
I let the license lapse when I was in graduate school because I had other things to do, though I never lost my interest in radio.
In 2003 or so I got my general license as KD7VEM.
I upgraded to Amateur Extra soon after and was assigned AD7GO (which I liked, but you can see how it would be misheard).
I got a vanity call sign KF7K, and I'll keep it until I die.
