So, today at lunch, we were talking about erted jokes.

One of my friends said 
"Mrs. ********** likes it hard.
You know, those music sheets she plays are hard to master."
(Inside joke)

First we were like

Then we were like

And then we're like

But then the security walks up to us.
"What are y'all doin, laughing so crazy?"

We told her
And then she went

So we all went

Then another security walked to table, and asks the same question.
When the first security told him, he went

So then, we tried to calm down

The bell rang and we walked out like nothing had happened.
