A four year old was at the pediatrician for a check up. As the doctor looked down her ears with an otoscope, he asked, “Do you think I’ll find Big
Bird in here?” 

The little girl stayed silent. Next, the doctor took a tongue depressor and looked down her throat. He asked, “Do you think I’ll find the Cookie Monster down there?” 

Again, the little girl was silent. Then the doctor put a stethoscope to her chest. As he listened to her heart beat, he asked, “Do you think I’ll hear Barney in there?”
