|1.||Speak to the organ grinder not the monkey.|
Wanting to talk to the boss not his sidekick.
Organ grinders being the boss, and the monkey being the one who helps him out.
Normally used in a conversation to describe the 'monkey' as someone who's interfering and defending or covering for the the 'organ grinder'.
Shut up! I wish to speak to the organ grinder not the monkey.
