Alright, I have a pretty damn good one.
This year in my math class we had a sub and she is a complete dumbass. She's about 75 years old and clearly something just not quite right with her. She was playing videos for us on youtube the last 10 minutes of class, when one kid in my class raises his hand and says "It's so and so's birthday today, could you please play the song "Birthday Song" by 2 Chainz?" So she goes on to turn it on full volume and it continues to blast...ALL I WANT FOR MY BIRTHDAY IS A BIG BOOTY HOE hahahaha. Best day of math in a long time.
