David Gregory Drunk on Radio Show?

Lots of interesting odds and ends in today's news, including the news that David Gregory called in to the Don Imus show from India, acting so bizarrely that it appears he may have been drunk.

Perhaps he'll blame it on jet lag?

Update: Well, the jet lag excuse didn't take long to show up on the 'Net.

Further Update: NBC News says Gregory wasn't drunk.

I've now heard the tape, and if he wasn't drunk, his giddy behavior was certainly not that of a professional representing NBC News in its best light.
