That's So in the House - S1.E16

When the President decides to make new uniforms for the White House tour guides, Raven shows up to help design them. When she has a vision of the hallway clock falling on the President, she tackles him to save her, but the clock does not fall. She runs away and the President has the whole security team trying to find her. Since Raven has to stay out of sight, Cory dresses up and pretends to be her to pitch her tour guide uniform ideas to the President.
