It is very important to ACTUALLY KNOW WHAT YOU ARE DOING when spackling a booth. If you simply give a bucket of spackle to Creidieki, and tell him "figure out what to do with this", you will not Win Booth. Particularly if he then enlists all of the freshmen.
Anyway, after you spackle something, you wait for it to dry, and then you sand over it, and then you paint it. Casual afterthought is then used to construct a roof and cover it in tar paper. Roof construction is oft-considered the best time of year to identify which KGB members are load bearing.
All of this might be fun, if it didn't cost more than KGB has spent on anything else, ever. That small detail guarantees fun.
