Simple! Easy! The rules are simple – if you had a skyscraper floor, what would you put in it? Why would it be special? Etc! 1st person does Floor 1, next Floor 2, and so on!

Floor #
This floor is home to bla bla bla. Why? Because yadda yadda yadda yadda yadda. Also, it has yabber yabber yabber yabber yabber. It also has yeah yeah yeah in it. Nah nah nah.
Floor 1
This floor looks like an ordinary hotel lobby by day. At night the laws of physics become rather malleable.
This floor serves as a prison for bad comedians. They are held in separate cells and are forced to write proper jokes. They are given a meal only if they manage to do that, every day. Most die of starvation in the end.
Floor 309
Marriage ceremonies of people with various types of fruits occur in this floor. The last one was the wedding of a man and a pineapple 2 days ago. The people in charge have quite a busy schedule apparently.
This floor gained its bizarre shape due to the blueprints being crumpled previous to its construction. Somehow, this went unnoticed by everyone right until opening day.
This floor has a giant computer that is able to do anything a human being can do!

Floor 312
There's a weird visual effect on this floor that makes it seem like your eyeballs are upside down and constantly spinning, which wouldn't be too bad if it weren't for the numerous twisting corridors filled with tripping hazards and funhouse mirrors. Barf bag dispensers are stationed at every doorway.
