What kind of face are you?

Last night one of the nurses asked Trevor how he was feeling. She showed him a chart with happy and sad faces. He studied it and when he didn't answer she asked him if he was a sad face or happy face? He said happy face. She asked which kind of happy face, this one (kinda happy) or this one (really happy)? He pointed to the really happy face as he was laying in bed eating a popsicle and watching a movie.
