So... there is gonna be a farewell party for a friend. It happens that this friend is really close with a cheating ex boyfriend of mine.

I happen to know he is going to be there with his recent ex girlfriend, one friend he cheated on me with and me.

I know him very well to know he is definitely going to make jokes about the three of us being there. He has already said that he has slept with half of the people there. I am sure he will try to make me feel uncomfortable, so can you guys help me with some funny come backs?
