Or a moment like this...

Int. Classroom. Mr. B sharpens pencils whilst Mrs. L prepares small group math materials at the back table.

Enter Mrs. D with child (J) in-tow. J was cleaning scuff marks off the floor in the hallway for some minor indiscretion and was caught by his mother - Mrs. D.

"Mr. B, I am sorry for what J has done."

"Oh, I didn't tell him to clean..."

"It's okay. J, come here. Sit on my lap."

Mr. B continues to sharpen pencils.

Mrs. D proceeds to spank J.

Mr. B continues to sharpen pencils, at a loss for what to do as he is taken completely by surprise.

And.....scene!

Possibly the most awkward moment of my short educational career. I don't presume to know much about parenting, but I'm fairly certain that's not the best disciplinary strategy...
