-No, I don't like it.
-There was something interesting there.
-What's that? Did the singer fall down from the stage?
-You are ribbing me! Really something intersting-there was a crazy music fan.
-How crazy?
-She went to the stage to send a bunch of flowers in fact, but she kissed the singer when he was turning his head to thank her. After that, the singer was a bit angry.
-Did he stop singing?
-No, he continued. Unfortunately, we found there was a kissing imprint on his face and we couldn't help laughing.
-That was impolite. You should have stayed out of this matter! 1） You are ribbing me! 你在开玩笑！
2） Stay out this matter please! 不要插手这件事情（不要加入这件事情）。 「请你猜猜看」挑战自我，情景抢答也刺激！ Here are three situations: S1. Your friend Peter is telling you an interesting joke. What can you say to him? S2.

Do you have any suggestion?
