<human>: So here I am, sitting in math class. Learning about shit I already learned 3 years ago. I decide to listen to some music and browse reddit. I come across [this] I think this is very funny and I start chuckling a bit. Now, when you have headphones in with music playing, what you think is a light chuckle is actually something a clown would sound like as it's butchering you. After the laughter dies down. I look around the class to see  everybody is looking at my with a disgusted look like I forgot to plug my headphones in before jerking off to some beastiality type shit. I take my headphones out of my ears and look curiously at my buddy beside me. He gives me a look of "I knew you were sick, but this is fucked" and I know IFU. I see my senile old teacher showing the first signs of emotion beside pure hatred and anger. He looks sad asf. He asks me what I think is so funny and before I can answer he says "I think it would be best if you just left". So I left. Turns out he was explaining that he was getting divorced.

Give me a shortened version of the text
<bot>: read a funny tifu in class, laughed out loud, saw a single tear roll down my teachers eye as he kicked me out.
