How about a "town" set up in the center with Pioneer Olympics? You could see how quickly they could get to each door on the 'street'--see how accurately they record statistics about the 'householder' .
Also you could have extreme weather like the blizzards of Upstate New York and you would be given 3 sets of tights and two denim skirts, a plastic bag to go over your tights at the foot and then a pair of socks. Then we would see how quickly the pioneers could get dressed and how long it would be before they worked up a chill by 'witnessing' on said street!
I'd also like to see a Window Washers set, where we could see who has the fastest squeegee in the kingdom!
The best part would be the Janitor Showdown. Each contestant would be assigned a theme-park restroom and at the end of the day we would see whose is the cleanest! During the day at surprise intervals, a Judge named Rutherford would roam the park and check to see that all of the stalls had toilet paper!
