The number one expression has to be, "Behave yourself!". This is commonly used by parents on their children. Some other common expressions would be, "Behaving Badly", "Behave like a lady (gentleman)".

You can also use "behave" when referring to the function of a machine or computer programme and how it works

except behave yourself
