I've never forgotten the wave of emotions I felt, for a girl in my 5th grade class. I didn't like the teacher at all at first, in this new school in a different country. Ms. or Mrs. Manning made most all the kids stand up in front of the class to read or recite their "reports" on assigned reading...especially the shy ones.
Anyway, this girl was so scared and uncomfortable up there having to do that that she lost control of her bladder. Some of the kids were laughing and jeering, before Ms. Manning tersely silenced them and very gently got the girl out the door. I don't remember the girl's name, just the horror and humiliation on her face. After that though, I really liked Ms. Manning.
(Sorry, I do realize that huge farts are a "funny" subject.)
