Washington:
The US presidential seal fell off Barack Obama's lectern on Tuesday and fell onto the stage as he delivered a speech at a women's conference in Washington.
"That's all right, all of you know who I am," the president joked when he realised what happened, prompting peals of laughter from the audience.
"But I'm sure there's somebody back there that's really nervous right now, don't you think?" Obama added, referring to the person who had hung the seal on the front of his lectern so precariously.
"They're sweating bullets back there," he said, laughing.
The incident happened about halfway through Obama's speech to Fortune magazine's Most Powerful Women Summit on Tuesday night at Carnegie Mellon Auditorium.
