Mr. Ashley and I were talking after work and he mentioned that he needed to go into work early on Turdsday. We frequently call it that thanks to years of listening to a funny local radio program in our area, I know others who do it too. (Justifying here.)
Big Kid interrupted us from across the room and said, "Do you fink you two could start sayin' "Fursday"? I don't need a little brudder who finks Turdsday is a day of da week."
It usually irritates me when he corrects me, but he actually has an excellent point.
