McKayla Maroney's unhappiness in only taking silver on the vault was perhaps the best thing to come out of the 2012 London Olympics.
Maroney scrunched up her face in displeasure on the medal stand, setting off an Internet meme that put her "not impressed" face in all kinds of funny situations.
So, when Maroney and her "Fab Five" gymnastics teammates visited The Late Show with David Letterman to bask in their Olympic success, it was only a matter of time before Maroney's other reason for fame came up.
Maroney, who has shown her ability to poke fun at herself and the Internet sensation before, was quick to oblige. See what she and her teammates had to say — and do — about the "McKayla is not impressed" phenomenon in the video below.
