My mom loved to sail and came back home many times sunburned. A couple weeks before I had been sick and when I said Mom it sounded like "Bob" because of my stuffy nose. So one day she came home sunburned and we had been calling her "Bob" and Lisa and I looked at each other and said Bob, you look like a lobster! And then right after that, Bob the Lobster was born. We would call her BTL or just Bob for short.
