You are funny, aren't you?
This is a Tag Question. The whole sentence is called "tag question" whereas the end or tail part is known as "question tag". Tag questions are very common in now a days English. You must hear them in movies and TV shows. But sometimes they sound funny or strange to ESL Learners. For instance in case of "I" we use "aren't" e.g. I'm the funniest, aren't I?
Some other tag questions could be like.
She is beautiful, isn't she?
He will come today, won't he?
They have eaten their meal, haven't they?
She isn't coming, is she?
John will not agree, will he?
They haven't eaten their meal, have they?
Please note the difference. If first half is positive the question tag should be negative. And if first half is negative the question tag should be positive. This is general rule but as you all know English is a Funny Language so there are "funny exceptions" too.
