Once a Minuteman, always a minute man.

Former Celtics head coach Rick Pitino testified Wednesday that Karen Sypher, the woman accused of extorting him, initiated the sexual encounter they had in 2003. Pitino alleges that Sypher’s intent was to use the sexual encounter as blackmail against him. Pitino also alleges that he doesn’t have much stamina. (USA Today)

Staring straight ahead and not looking at Sypher, Pitino — the married father of five — acknowledged that he made a mistake when he had a brief sexual encounter with her at Porcini restaurant after it closed the night of July 31, 2003.

He said it began when she started rubbing his leg as they were sitting at the bar, then suggested that they go to a booth. “One thing led to another,” Pitino said.

He said he got nervous after Sypher told him she was very fertile and joked that her first husband once got her pregnant just by looking at her.

“Our encounter lasted less than 15 seconds,” Pitino said.

Pitino graduated from UMass in 1974 as a Minuteman. 36 years later, he can’t even make it that long.

By the way, if some chick told me she was very fertile before I ever had sex with her I’d be out the door and running away from her faster than Pitino can say, “Umm, sorry, but I already finished.”

P.S. – Ron Jeremy’s not walking through that door.
