Tenet 'A', derived from the Constitution of the United States of America, holds that Barack Obama became the U.S. President at twelve o'clock eastern standard time on January 20th, 2009, even though he hadn't been sworn in yet.
Tenet 'B', derived from racist crazy people, holds that Barack Obama was never the U.S. President on January 20th, 2009 because he didn't give a clean reading of the oath of office until the following day.
Given that Tenet 'B' represents a lingering devotion to a former president who willfully ignored his country's Constitution throughout two full terms in office and that Tenet 'A' represents said document, the two tenets cancel each other out. Thus emerges Tenet 'C', derived from Stephen Colbert.
Tenet 'C' holds that whatever person (or thing) appeared on camera as part of the live television broadcast of the presidential inauguration ceremony at noon EST on January 20th, 2009 automatically became the President of the United States; ergo, famed cellist Yo-Yo Ma was the leader of the free world from Tuesday to Wednesday (before Obama retook his presidential oath).
However...it turns out that even that airtight logic is only half true, at best.
At noon EST on the aforementioned date, when the world was seeing Yo-Yo Ma perform John Williams' "Air and Simple Gifts" as part of a quartet, they weren't actually hearing it; rather, they were hearing a pre-recorded version of the song.
This nationally-televised deception begs the question: Who the hell was president between January 20th and January 21st?
The only conclusion is that there were two co-presidents during that time--a Chinese artist born in France and a stereo system assembled in the United States.
(Boy, did we Americans miss a window to get away with some major felonies.)
