If you use TT, you know that there is a little motivational character on the upper left side of the screen that cheers the student on when s/he gets a correct answer. Usually they say things like "nice job" and "way to go."
Today, DS chose the little bust/statue guy. After getting several answers right, DS asks me, "why is he saying I'm a NACHO????"
:D
He was actually saying, "You're a natural!"
