Jim Crow
We are sure that this name sounds familiar to you. You might not know Jim Crow, the theatre character, but you have probably heard of the old segregation laws named after him. It is probably the most notorious instance of blackface ever. Mind you, and he was played by a Caucasian guy called Thomas D. Rice.
John Doe And Jane Doe
In case you did not know, John Doe and Jane Doe are not immortals who keep dying repeatedly. No, criminal investigators use these names when they have yet to identify the bodies. You have probably already figured that John Doe is used for guys, while Jane Doe is used for women.
