Do you remember the reporter who started talking nonsense during a live remote? It was later determined she had a migraine, not a stroke. Then another fellow got the babbles on TV, although this seems more like he just became affected with extreme self-consciousness and had a bit of a panic attack. Here's the incident, replayed on the Jimmy Kimmel show, with audience reaction. It's funny when people might be having a stroke!

Now there's this:

According to a Radar online, a source said "She was just sitting on the stand during her show taping and she started saying things that didn't make any sense." Don't chicken on my neck and tell me it's Thursday! Then: "She said, 'I need to stop, I'm not feeling well."

She later told TMZ it was exhaustion, and told the world via Twitter that she's okay. She also said this:

I'll be back taping April 18th. All my tests were negative. I feel fine! Fired the doc though, telling me "ummm..", not an answer u fool!

Glad to hear she's fine, but this spate of professional talkers who lose their ability to talk when the cameras are rolling is the sort of thing you see in the first 20 minutes of a sci-fi film. Someone finally realizes it's happening all over the world, because of cosmic radiation, so they have to send a team of attractive astronauts to Saturn, or something.
