In common

Today, Doug and Miguel were talking about Indiana Jones, whom Miguel is fascinated with. Miguel wanted to know if Indiana was his real name. Doug explained that no, his name was something else and Indiana was his nickname. To which Miguel responded:

That's just like Frederick Douglass. Douglass wasn't his real name, either. He was a slave, but he escaped and the slave catchers were trying to find him. But they were looking for Frederick Bailey, so he changed his last name to Douglass to make it harder for them to find him.
