Interesting thoughts...I never found his phone call smug per se, just him having a little fun, knowing that he was about to become the first Millionaire. The way he threw his arms in the air in a "No, duh!" kinda way irked me a bit, but again, him making TV history kinda grants him carte blanche IMO. :-)
Now, you wanna talk smug? How about the guy who took a shot at the Million Dollar Question during the 10th anniversary week and lost? It took balls, and I give him credit for that, but man was he cocky!
