Expanding the traditional "School for the Arts"

I passed a school for the Arts the other day that listed all of the activities that they taught.  Among them were the normal: voice, various instruments, dance, and painting.  The one that stuck out to me was "Yo-Yo!"  Who the heck sends their kids to school to learn the Yo-Yo?!  I'm sorry, if my kids are wanting to learn the Yo-Yo, they're on their own for that mind-bending activity.  I'm not paying for it!  After all, they have an Uncle back home that is pretty good at walking the dog (Yo-Yo trick).  One Christmas he walked the dog right up the christmas tree trunk and broke some ornaments.
