ask while knowing the answer knowingly ask the question

Looked at each other knowingly and quickly left.

to ask about something one already knows不过实际语境中都会这样: 如果是开玩笑的话就直接说You knew that!! 你晓得的！ You knew the answer!! 你明明就知道答案嘛!使用(过去式)表示对方明明就知道或是疑问句"Why do u ask me the thing you've already known?"你干麻问我你已经知道的事情?
