Possibly the worst invention in history. The double decker outhouse is, quite literally, two toilet stalls stacked. Although this structure conserves space, it is completely impractical and downright messy.
Bottom stall occupant: What's that creaking?

Morbidly obese top stall occupant: ... I think the floor is caving in.

Bottom stall occupant: *Sigh* ... who in their right mind invented the double decker outhouse?
