I was in a bus station and I had to pee. The toilet was rather dark. As I was walking to the urinal, I had to pass by the stalls and I thought I saw someone in the corner of my eye. Any way, I kept walking to the urinal and peed. Then I heard a man singing in one of the stalls. After I was done, I turned around, and I saw him smiling at me! He was sitting in toilet bowl, doing his big business. He said to me, 'See no doors!' Then I smiled and walked out. Mmm, that was pretty creepy!
