<human>: Happened earlier today. I just moved in with my girlfriend and I brought a bigger TV from my place. The lady decided that she wants my TV on top on this unstable bookcase in a sitting room that doesn't have a television. I told her "There is no way that this television is going to sit on top of that rickety book shelf" to which she responds "Fine, do whatever you want with it" and it was on. I hoisted the TV on top of this 5.5 foot tall book shelf and set it down. To my surprise the TV stayed just fine and it looked like I was going to be eating my own foot for dinner. Fast forward 35 minutes and I hear a loud crash from the other side of the house and immediately yell "I FUCKING TOLD YOU SO!" to which I hear a faint rebuttal and then silence. I walked into the sitting room to find my TV in pieces on the floor and my girlfriend crying about how I didn't have to be such a jerk and how awful I made her feel. Now I will likely be spending my first night in this house on the couch, not watching TV.

Give me the gist of the text in a nutshell
<bot>: Tried to spitefully prove to my girlfriend that a large flat screen wouldn't be stable on a bookcase. Ended up with a broken TV and a night spent on the couch.
