Recite the Young Women's theme (from memory!). While holding cookies.
Wear a "High School Musical" tattoo on their cheek. For a week.
Wear PJ's to school and tell us all a bedtime story. About the most embarrassing thing they've ever done!
wear all of their clothes backwards and bake us all a cake shaped like a castle.
tell every single person who looks him in the eyes: "I just love you..." [note how he won't look at my camera? I'm hurt.]
drag around a pet shoe all day
more coming soon, I'm sure...
