The pilot on the small jet I took this morning was named Bobby. When you are responsible for the lives of more than 30 people at a time in your occupation, I think one should go with Robert, Rob, Bob or Burt/Bert. Thankfully, nobody had to yell in their Hank Hill voice, “Dammit, Bobby! Pull up on the stick!”
Bobby’s are ok for kids, ranch hands and guys who work regular Joe jobs like me. No pilots or doctors though.
