Obama learns a constellation's name

Over at Powerline, John asks: "How would he pronounce 'Cassiopeia'?"

Everyone knows that Barack Obama is lost without his teleprompter, but his latest blunder, courtesy of the Milwaukee Journal Sentinel, via the Corner, suggests that the teleprompter may not be enough unless it includes phonetic spellings. Obama was speaking at a White House roundtable on clean energy systems, and repeatedly saluted Orion Energy Systems, whose CEO, Neal Verfuerth, was present at the event. So Obama referred to "Orion" a number of times. Only problem was, he appeared to be unfamiliar with the word:
All terrific press for Orion, except that Obama kept pronouncing the company's name wrong, calling it OAR-ee-on.

Cassiopeia would be a good one, but I'd like to hear the big O pronounce these quickly in succession: Obama, Ohio, Orion, Onion.
