My youngest nephew (7 years old) said something and included the word "butt" in it except it didn't elicit the reaction he expected.
"You know, Gregory, just because you say 'butt' doesn't mean it's funny. You can't just say 'butt' and think people will laugh," I told him.
"At school, they do," Gregory replied.
Going for the laugh, even in first grade, the little wisenheimer is on his way to class clown.
