Emergency room or mental ward?

I recently had to take a loved one to the emergency room.  As we first walk into the ER we see two security guards wrestle a screaming and fighting man down to the floor and restrain him.  While sitting in the waiting room we saw a man repeatedly pluck a single eyebrow hair, blow it from his finger tip, quickly reach out, catch it, and slap the single hair back onto his face.  We also saw a man in a very brightly colored neon green shirt wearing dark sunglasses, playing an invisible drum set.  I am not quite sure why but for some reason the cymbals were located behind him.  So we watched him frantically playing the (again invisible) drums directly in front of him.  We tried not to laugh when he turned around to strike those important cymbals.  The best part about his show, is he was making the sounds with his mouth the whole time!  Never again will I buy tickets to a show, from now on I will simply take a trip to the local emergency room.
