Xiangsheng

Crosstalk, also known by its Chinese name xiangsheng (Simplified Chinese: 相声, Traditional Chinese: 相聲, pinyin: "xiàngsheng", literally, "looking at each other and speaking"), is a traditional Chinese comedy form. Crosstalk is a special kind of dialogue and a special kind of performance.
The comic language has many puns and allusions. The words are spoken in a fast, rushed manner. The comedy is a kind of banter. 
According to Canadian crosstalk comedian Dashan (Mark Rowswell), the closest equivalent in English would be Abbott and Costello's "Who's on First?" sketch.
