Tom, your agent called. She said "Shut Up Already!"

NEW YORK (AP) - Tom Cruise criticized NBC "Today" show interviewer Matt Lauer on Friday when Lauer mentioned Cruise's earlier criticism of Brooke Shields for taking anti-depressants. Cruise told Lauer he didn't know what he was talking about. "You don't know the history of psychiatry. I do," Cruise said.

The interview became more heated when Lauer, who said he knew people who had been helped by the attention-deficit disorder drug Ritalin, asked Cruise about the effects of the drug.

"Matt, Matt, you don't even - you're glib," Cruise responded. "You don't even know what Ritalin is. If you start talking about chemical imbalance, you have to evaluate and read the research papers on how they came up with these theories, Matt, OK. That's what I've done."

Wha-wha-wha-What? Tom Cruise knows the history of psychiatry? He feels qualified to discourage the taking of anti-depressants?

Some folks are pretty and can act. Hold onto that, Tom. The first won’t last, and being hired for the second will be in jeopardy if you keep running your mouth.

Everyone… please keep taking ALL of your medications as prescribed unless you’ve discussed your decision with your doctor. But you know what? Don’t go by me. Do what you feel is right.

But don’t go by Tom either. Or Matt. Or Al. Or even Katie.
