Seriously. If you say diarrhea, people will not question you
  1. When a cop pulls you over
  2. As the reason you were late for work
  3. When you don't feel like going to work
  4. When trying to avoid talking to people at a social function
  5. When you made plans but suddenly the couch is more appealing
  6. When you're stuck in trivial conversations with neighbors you don't really care to know
  7. To skip the bathroom line at large events
