Evidence

Although he claims he didn't do it, there is evidence that Jack got into the Nutella today:

1. There were small, brown footprints on the floor in the kitchen
2. Chocolate was smeared all over Rudi's back
3. Jack was COVERED in Nutella
4. The Nutella jar was open and in Jack's reach
5. There was Nutella on the wall at about the same height as Jack's waist
6. Jack's lips and teeth were brown
7. There was a spoon covered in Nutella in the silverware drawer
8. Jack has done this before

I'd say he did it(:
