Mr. Clumsy's Christmas is a story from the 1980 Annual.
Plot[]
Mr. Clumsy is putting up his Christmas decorations; that easily spells "catastrophe" when your name is "Mr. Clumsy"! For instance, he was climbing the step-ladder with four steps but mistakenly assumed there were five! He fell off the ladder and landed on a branch!
Mr. Chatterbox arrived shortly after to help Mr. Clumsy with the decorations. But helping Mr. Clumsy out to Mr. Chatterbox was merely watching him make a clumsy mess! Mr. Clumsy tried to hang a paper-chain only to hammer his finger and have the chair he was standing on fall to pieces. Then when Mr. Clumsy tried to hang up his Christmas stocking, he landed in the sooty grate. Mr. Chatterbox left soon after, wishing Mr. Clumsy a "Happy Christmas!" So much for helping out Mr. Clumsy.
