Shut up

Look what I just read in the Sun-Sentinel.

Rafael Palmeiro still isn't sure why he tested positive for steroids, he told The New York Times. Palmeiro was suspended in August for 10 days by Major League Baseball. "I wish I could pinpoint exactly what happened," Palmeiro told the newspaper. "I would think it was the B-12. I'm not certain of that; I can't prove it."

Just. Shut. Up.
