My earliest stories are from my special ed days when I worked one-on-one with kids. This particular day I was working with a kid in developmental first grade (in our school, that's the grade between K and 1), quizzing him on the letter O.
The card for the letter O had a picture of overalls on it so he could learn the long sound better. This poor guy had NO CLUE what overalls were (kinda surprising in Indiana, huh?), so I would say,
"What letter is this?"
"What word helps us remember long O?"
The correct answer would have been "overalls," you know, to go with the picture.
This kid's answer: "OVERBALLS!"
Okay, so we didn't stick with "overalls" after that...lost cause.
