In my 15 years of teaching...

When the teacher sits on her desk and says this, you *know* the entire class failed.

Friend: hey what did you get for math finals
You: I's got an f+
Friend: Oof
You: ikr
Teacher: *sits down on desk*
Friend: oh no here it comes
You: what comes?
Teacher: In my 15 years of teaching... I have never seen so many people fail the finals. It's literally THE FINALS!
*continues ranting for 3 hours*
Teacher: *takes a deep breath* Ya get that!?
Everyone: omfg finally
