"No way! There could be weevils in there.."
When you try to pick up the box of healthy wheat cereal, Tim won't pick it up because he's afraid there might be weevils inside. This refers to a post on the Double Fine Action News page where Tim found a dead weevil in a box of Kashi.
Also, when Tim picks up the Psychic O's box, he comments that he loves the cereal because the weevils won't touch it.
