A guy passes a Psychiatric Hospital

As he walks by, he hears people inside chanting "33! 33! 33!" Curious, he walked over and put his ear to the wall. He still heard "33! 33! 33!" He saw a small hole in the wall and decided to look through. As he stared into the hole, a finger suddenly came out and poked him in the eye Jumping back in pain, he started running away. As he ran, he heard the people chant "34! 34! 34!"
