“My body is ready” is a quote associated with Nintendo's then-executive Reggie Fils-Aime who, during the initial presentation (E3 Press Conference, July 11 2007) of Wii Fit and the new Wii Balance Board, uttered the phrase “My Body Is Ready” before stepping onto the board for a demonstration. See for yourself:

I don't know why, but I love this quote and I've been overusing it ever since I learned of its existence. It is beautiful. I know it's kinda weird and I know that's also kind of the point, though many seem to think of the quote as implying something sexual, a context I have never even considered using it in.
