Nick Diaz showed his sense of humor Saturday night, sending out a message via Twitter in reference to a previous comment made by Georges St-Pierre. GSP returned to action with a decision victory over Carlos Condit in the main event of UFC 154: St-Pierre vs. Condit.

"I am not impressed by your performance (St-Pierre)," Diaz posted following the event.

Diaz was defeated by Condit earlier this year in a bout for the interim UFC welterweight title. Diaz and GSP have been scheduled to face each other twice, but both bouts have been cancelled.

St-Pierre was asked about the Tweet during the post-fight press conference, saying, "I did better than Diaz againat Carlos."

Back at UFC 63, St-Pierre entered the Octagon and told Matt Hughes that he was not impressed following Hughes' victory over BJ Penn.
