I thought it was fascinating to watch. Stephen was pinging off the walls from the start, he clearly was extremely rattled by the uncertainty of the whole thing. An extended disturbed, but still funny, monologue, followed by Sanjay Gupta discussing things that were strange at the time, but have become very familiar. An episode for the time capsule, for sure.
I'd like to see the show from his bathtub again sometime, but as for tonight, I'm ready to return to the Ed! I expect Stephen will be pinging again, only this time from happiness!
