Here in England, they use the phrase "cheeky monkey" for children, and today i had a great example of why--
i've been saying to Elias, age 4, "how many times should grandma have to ask you?" --to obey, to stop, etc.--the assumed answer being "Just one," reinforced by my one raised finger.
Today he was sticking stickers on my, um "lady bumps." i asked him to stop a few times, then said, "Elias, how many times should grandma have to ask you?" He did a sly little grin up into my face and answered innocently, "two?"
Cheeky monkey! i've gotta admire his style, though. ;-)
