The Brain and the doctor

I took the Brain to the doctor today. He had a slight fever and a croupy cough. You can tell when the Brain doesn't feel well because he is very sluggish. He climbed up on the exam table and laid down. He usually jokes around and goofs off for the doctor, but not this time. He didn't move and barely spoke the entire time we were there, which is very unusual for him. As the doc began her exam, she said, "This is quite a handsome boy you have here." The Brain uncrossed his arms, snapped his fingers, and gave her two thumbs up!
