My supervisor walked past my desk laughing like a hyena. When I asked what was going on she nearly popped a stitch repeating her encounter with a co-worker in the women's restroom. She was standing there washing her hands when all-of-a-sudden a man walks out of one of the stalls and moseys up to the sink to wash his hands. He apparently realized something was wrong when he didn't find any urinals in the stall but that didn't stop him from completing his business.
