3 Fingers

My 3 year old Granddaughter was watching one of a few TV shows she is allowed to view, and it was Mickey Mouse's Club House where Mickey was teaching the tuning of his ukulele (GCEA) using a pitch pipe (she picked up on her Grandpa playing Wheels on the Bus).. first off who knew Mickey played the uke?? And second, how does he play 4 finger chords?

If he showed you, that program would probably be taken off of your granddaughter's "approved TV watching" list...
