Hi there! It's been a wile since the last time I visited this site! I saw your post and its a very interesting question!(btw I'm Dutch so sorry for grammar mistakes)
If my girl friend would have a Pinocchio nose curse I would wait for us to come home after a long day at work and when we have dinner I would ask her uncomfortable questions hoping the get her to tell some small fibs that makes her nose just grow an inch or two longer.
At this moment it would make her so uncomfortable that you can hear her hearth bounding because she doesnt know how to get of this and she would now tell a big lie to cover up her lil fibs and then hoping that her nose would shot out to banana sized length.
Getting some shock reactions, blush red face. touching and rubbing her nose in shame.
Oh that would be a dream...
