Matt and Dave

Two stories follow the adventures of a naughty boy named Yuck who employs pet worms and practical jokes to disgust and annoy his prissy sister.

In the first of two stories, a naughty boy named Yuck starts an odorous new club, much to the disgust of his sister; and in the second, Yuck goes to revolting lengths to prove that he is really sick on the day of the class spelling test.
