What’s the funny point in this joke?

Ron Artest and Kobe Bryant clashed. In the post-game press conference, Artest said that he and Kobe had never been friends, and then left the meeting angrily.

At this time, Yao Ming said very nonsensically: "I'll see you in the club." (See you at the club)

Artest left angrily because he actually wanted to go to the club early.
