What is aye aye sir?

Aye aye sir is a common naval phrase used to acknowledge an order or command given by a superior officer. The phrase is derived from the nautical term "aye aye," which means "I have understood and will comply with your orders." It is considered a sign of respect and professionalism to use this phrase in the military or naval contexts. The aye aye itself is also a type of lemur found only in Madagascar, known for its unusual elongated middle finger used for finding and extracting insect prey from trees.
