My first boss after college graduation was named Lonny. He was a real piece of work as well. The other people in the outfit were pretty decent or I wouldn't have stayed even the 16 months which I did.
To this day, I find myself doing things that irritated "Lonny."
People name their kid “Lonnie” because they already used Ronnie, Bonnie, Connie, Donny and Jonny.
