<human>: This prank war has been perfect. Nothing has been seriously damaged and there are no injuries so far. My last prank was a little mean; I put a mouse trap in his protein powder jug. When he stuck his hand in the jug I heard the snap upstairs. He had just stolen all my lightbulbs, so I wanted to be mean. 

So last night I drank too much. I work at a bar, so Sunday and Monday nights I go out because I work every other night of the week. My roommate knows this. I went out. I don't remember getting home. 

As my eyes opened, I thought 'oh...these aren't my sheets. That is not my dresser. OH SHIT I SLEPT WITH SOMEONE' (I have a girlfriend whom I admire). I quietly checked to see if there was another human in the bed with me, to see if I needed to sneak out ninja-like or if I could just run, and thankfully there wasn't. I sprung out of bed and grabbed my phone out of my pants to call my roommate and noticed my desk. It was my stuff... But not my desk.

Summarize the given text in a few sentences.
<bot>: My roommate bought shitty IKEA furniture, rearranged my room, and changed my sheets to make drunk-hungover me think that I slept in someone else's room.
