Shit happens! While driving my car on the way home after work, I heard a big bang on the roof. It was so loud that I thought I had been hit by meteorites or something. Suddenly, I realized that it was a thick layer of birds' slimy shit which kept dripping down from the roof. It was so thick that no matter how hard I tried to wipe it off with the windshield wipers, it still remained on the windshield. Alas, it never rains but pours.
