Stella's misery regarding the Three Stooges reminds me of a similar episode in one of my summer classes. I share it mainly for the Humor.
I taught one of those intensive summer session classes that meets three hours a day, five days a week. Normally, I give the students (and myself) a break in the middle of these classes.
I'm white (that's important later). I had a number of African-American students in my class, several of whom had been in my Freshman Comp class either the semester directly before or two semesters earlier. All of them were athletes. Two of them, let's call them James and Madison, sat next to each other.
One class, James showed up, but not Madison. I noted this on my roster and we started class. We reached our break, and everyone scattered to the four winds (hat tip, Yaro). Per usual, I noticed James on the phone as soon as we reached our break. When we reconvened, I found Madison in James's seat.
Not only was Madison in James's seat, but he was dressed identically to James.
I stared at Madison as the class reassembled, wondering if James would reappear. Nope. No James. Only Madison.
Struck by a sudden inspiration, I said to Madison, "Hey, Madison, where's James?"
"Yo, Miz D," he responded, "I don't know. We were, ah, just splittin' the class up today." (Seriously, he said this.)
"Madison," I continued, "is this one of those you think that I think all black people look alike deals? Like...I wouldn't notice that you were Madison and not James?"
Madison shakes his head slowly and says "Yeah, it occurred to us."
I pointed out that first of all, I didn't think all black people look alike..."Geez, man, I lived with a whole village full of black people and I could tell 'em apart!" and also that if I was going to mix up two students, black, white, or green, it probably wouldn't be the two that I'd ALREADY HAD FOR TWO SEMESTERS.
James and Madison were properly chastened and both attended class henceforth.
