President Obama possibly caught singing with Stephen Colbert

We're sure this isn't President Obama's worst hot mic moment of his career.

"We'll meet again. Don't know where, don't know when."

That, according to the YouTube description, is President Obama and Stephen Colbert practicing for Colbert's final show which aired last week.

Of course, there's no way to verify this, but the description says their mics were still live and transmitted audio to the media room at the George Washington University facility.

And while Colbert did have quite the star-studded cast singing that little song for his final performance, Obama was not among them. So it's not exactly clear where this little duet ended up.

The two were on the GW campus for the filming a "The Colbert Report" episode earlier this month - one of Colbert's final episodes before he takes over for David Letterman on CBS next year.
