Can you share some funny true teacher stories?

One story I read on BuzzFeed was about a teacher who accidentally sat on a whoopee cushion that a mischievous student had placed on the chair right before class. The look on the teacher's face was priceless as the whole class burst into laughter.

Once, my math teacher was so absent - minded. He walked into the wrong classroom at the beginning of the class and started teaching calculus to a group of freshmen who were supposed to have English class. It took him a good five minutes to realize his mistake when students kept looking at him strangely.

One story is that a new teacher walked into the wrong classroom on the first day. He started introducing himself and the subject he was supposed to teach. After a few minutes, the real teacher of that class showed up and they both were very confused at first. Then there was a lot of laughter from the students.

Sure. There was a teacher who always mixed up students' names. One day, he called a boy named Tom as 'Tim' all day long. Even when the boy corrected him, he still got it wrong. It was really hilarious.

Once, a teacher was teaching math. She was so into the lesson that she didn't notice her skirt was tucked into her underwear at the back. When she finally realized it after walking around the classroom a few times, she blushed deeply and the students couldn't stop giggling for the rest of the class. But she took it in good humor and laughed along with them later.

Sure. Once, my math teacher was writing on the blackboard and his pants split right in the middle of class. He didn't notice at first until a student pointed it out and the whole class burst into laughter.

I heard about a parent - teacher conference where the teacher was concerned about a child's messy handwriting. The parent just smiled and said, 'Well, you see, he's left - handed and we have three cats at home that keep running across his paper while he writes. It's a battle zone at the homework table!' This light - hearted explanation diffused the tension and made the teacher see the situation in a more humorous way.

Once, a science teacher was demonstrating how to make a volcano erupt. But instead of a normal eruption, the mixture exploded all over his face and lab coat. He just stood there with a look of shock which made the students laugh hysterically. This teacher took it in good humor and later laughed about it with the class too.

Once, my friend thought he could impress everyone by doing a skateboard trick. He climbed up a ramp, tried to do a flip, but ended up falling flat on his face. It was so funny yet true.

A preschool teacher had a box of toys for the kids to play with during free time. There was a toy that made a really strange noise when you pressed a button. One child found it and started pressing the button over and over again. All the other kids gathered around and started dancing to the strange sound. The teacher just watched and laughed at how creative the kids were being.
