<human>: I moved out of my old apartment into a new house. It's just me, one roommate (we're both male), and my dog. Now here's the problem... it's a 3 bedroom house for only two of us. What should we do with the extra room?

I'm not very creative so I don't have any idea. I hate the fact that there is an empty room just sitting there going to waste.

Here's some info that might help you guys come up with some ideas:

We're college students. We already have a beer pong table in the garage.
We go to the gym at our school so we don't need an exercise room.
We only smoke outside or in the garage and will not ever be smoking in the house.
I am willing to spend some money on a good idea as to what to turn this room into.
It's a 10x10 room with a sliding door closet.

Provide a brief overview of the text.
