Not sure why I found this humorous. I feel the Pikachu shitting and spewing out blood at the end after falling over is a tad bit overdone as a joke. The only way I could see Nurse Joy really doing that stuff is if she was having an off day and was done with everyone's attitudes or if she was just really wanting to goof off and not do anything for the day.
The animation was pretty good, kind of wish the background music was available for download though, found that pretty funny actually.
