Not the teacher but this one time in 6th grade a friend of mine called me for help with science homework. It was about the early universe and the question was like how do we know things about the early universe and I said "Because there was a guy, Dr [some made up name] alive back then and he kept records." And she fucking put it down and turned it in.
That reminds me. Your story is better, but I've got a similar one.
We had a long training meeting at work and a multiple choice comprehension test followed. However it was very informal and the employees were encouraged to work together on it.
The last question on the test was simply, "Did you learn today? Yes, No."
Obviously the answer is supposed to be yes, that you comprehended your training.
My buddy was pretty much
completely unengaged and just fishing for answers. Not even bothering to read the questions. Turned and asked me what the answer to the last question was.
"B, no. It's no."
They promptly circled "No" and then to my surprise turned around to a group of ~7 other slackers and told them all the answer was no, and they all excitedly finished their tests as well. They then happily signed and handed all their tests to HR.
I started cracking up real hard and told my buddy what happened after they inquired about what was so funny.
You just signed a paper to tell HR that you didn't learn shit, dumbass.
