First thing you need to know is that my instructor is very modest and naive...
My instructor was asking what we were doing for our Christmas break. When we asked her what she was doing she informed us that she was taking her niece to see Santa at the mall. We asked if she was gonna sit in Santa's lap and ask for a gift too. She said, "Yes, I feel HO HO HOish." Everyone in the classroom fell on the floor laughing. She had no idea why we were laughing. After she repeated the statement to herself it became clear why it was so funny. It was definitely a "Remember When."
