My little sister, at the age of three, would react to something by saying "gasp!" and put her hands to her mouth. It was so strange, cause no one ever used the word "gasp" so we never knew where she got that one from.

Pope John Paul visited Australia back in the '80's and we saw him at a street parade. My other little sister, also about 3 y/o called out "It's the Coke! The Coke!"
