I'd give them a tour if they'd have asked me nicely and told me the three magical words.
Firstly, I'd show them my wall of shame, mixed in with my wall of fame. And the tiniest corner of said wall would be called 'wall of pride' which would be impossible to notice on first glance, and is still quite hard to notice even when you stare at it point blank. Its contents are not too impressive either, compared to the rest of the wall.
Secondly, yet another wall where there's random footage viewed, and it changes each 5 seconds. It's quite intriguing just staring at the wall mesmerized, and you could most likely stare for days and days on end and never find yourself bored, but you would force yourself back into reality soon enough. You'd probably smile and laugh a lot more than usual, than you would before watching.
Lastly, you would notice the 3rd wall and last one which does not contain an entrance and can thus not be filled up. The 3rd wall would stack up several studio equipments, amplifiers, guitars, pianos, all kinds of instruments that plays constantly, not leaving a single nanosecond without a tone. Again, it's quite entertaining, especially when the instruments attempt their own accords and lyrics, rather than recorded songs from the outside world. But, you'd find it hard to concentrate at any given time, and wish you could turn down or even off the volume at times. But, there is no mute button. It plays non-stop whether you like it or not, wherever your mood lies.
I doubt people would ever wish to visit the room again.
