Query: Oh that Harold

Harold's messy adventures have resulted in a lot of pain and suffering in my household. Purple crayon everywhere. You could say the blame falls on me for leaving purple crayons in easily accessible areas of the house, but I prefer to blame a children's book. Harold seems to be a stand up little fellow, but I shant be purchasing any more Harold adventures that involve colored paraffin wax.
