My mom called me one time when she was babysitting our son. She was frantic. She said, "He's crying and wanting "waygo box. What does that mean?!!! I laughed out loud on this one. He was wanting his "Lego Blocks". Everytime she repeated back to him what he said, he would say NO and cry louder. He's 31 now and we still sometimes call them "waygo box" just for the fun of it.
