Input: Text: this will be short. i decided to post this in the spirit of the recent post about offending an unfortunate looking man in a starbucks. basically on thursday my spanish teacher decided to give us a lazy day in lue of it being the eve of spring break. a couple people suggested that we show some videos of hilariously bad rap battles to kill the time. i quickly suggested a youtube classic, featuring two kids, who may or may not be mentally handicapped, going at each other with sicknasty burns.

while this video was playing, everyone seemed to be having a laugh, and i mean a big one. people were stepping outside for air, literally falling out of their chairs. (side note, literally half of my class is compromised of potheads, so this shit is common.). well, halfway through, i notice my friend's face is slowly adopting the complexion of a bruised tomato. i ignore him, thinking that he's having similar conniptions as the other people in my class. no. turns out that he has 2 or 3 siblings with serious mental handicaps, and i basically trivialized and insulted his family. unfortunately this comes weeks after i made an ill advised abortion joke about trisomy kids. i wasn't even trying to be edgy, the joke was just there! 

video in question: https://www.youtube.com/watch?v=tkkxptp6xjq

TIFU By playing a youtube classic with the wrong audience.
