people who love fingering the g string, moving their hand up and down the neck of the instrument and making noise from the F hole.
violinist to cellist: wow, you get paid so much for keeping your legs open and making noise from your F holes.
violist to violinist: its so much harder to finger my G string over yours
bassist to violinist: i've got a much bigger and longer neck on my noise maker than yours.
us string players love F holes.
