Don't check your humor at the door.  Bring it in.  According to research, a good laugh can provide up to 45 minutes of relaxation (source below).  I recently discovered Dave Smith, and he's great!  Life can be rough.  Trust me, I know.  I've drank my own urine to survive.  It tasted exactly what you think pee would taste like.  Take time out of your day to laugh.  Tell a joke from time-to-time.  It's good for your health.  Enjoy Dave Smith!
