Emma Watson, on Dave Letterman, 11/15/2010.

I’ve done this more times that I can count even when I’ve tried making myself practice saying eraser instead of rubber, but it’s as second nature as breathing. That’s another mistake I make what with my british english background. Thank goodness most of my college classmates aren’t very quick with the colloquialisms and frankly don’t care. I find this highly entertaining. :D :D
