Nicknames

Black Male Student:  "Mrs. A, do you have any lotion?  The Negro Knight can't be ashy."
Me:  "What now?  Did you just call yourself The Negro Knight?"
Black Male Student:  "Yes."
Me:  "Who gave you that nickname?"
Black Male Student:  "I gave it to myself."
Me:  "Of course you did."
Black Male Student:  "Either way, I need some lotion.  A rule of being a Negro Knight is that you can't be ashy."
Me:  "What are the other rules?"
Black Male Student:  "I don't really know, but I know that needing lotion so I'm not ashy is the fourth rule."
