Oh yeah, I definitely have said something under my breath and was caught.
For some reason I still remember it clearly.
I was in the 3rd grade and we were playing "Heads-up, Seven-up" while the teacher was talking to the other teachers in the hallway.
I got mad at one girl for some reason, and feeling slighted, I called her a bitch under my breath while she was walking away from my desk.
Unfortunately, I think I was a heavy breather and several kids, including her, heard me.
The teacher was told post-haste, and I found myself on the receiving end of her paddle, made to stand in the hall til class was over, then was whipped by my father when he came home.
I try to wait to do my mumbling out of ear shot now.
