 Eddie is feeling left out in school. Eddie s teacher, Miss Lister - who is really Mrs. Rogall - is pregnant and the mothers of her students are planning a surprise party for her. Of course, Eddie does not have a mother. Miss Lister finds out about Eddie s troubles and the party when Eddie writes her a note stating that since he doesn t have a mother, the only thing he can provide for her party is his father. In fact, "Mrs. Tom Corbett" receives a letter asking for her assistance in the party. After conferring with Miss Lister, Tom does decide to become Eddie s mother for this function. The other mothers are reluctant to let Tom into the party organization because of his gender and his supposed inability to do motherly things, like make finger sandwiches, or what Eddie and Tom call fingertip sandwiches. But Tom, after refuting the statement by organizer Mrs. Harris that the party is not one for "the ladies" but rather for Miss Lister and her class, does join in and volunteers to make such sandwiches for the party. The other mothers still think that Tom will ruin everything for the party. Tom very well could as he has no idea what are in finger sandwiches nor does he want to enlist the help of a female, even the help of Mrs. Livingston, in making them. But seeing that the food is for the children, Tom takes his cue from the sandwiches that Eddie makes for himself. The results may not look pretty, but end up being a big hit not only among the children, but also Miss Lister and the mothers. The sandwiches consist of chopped hot dog, peanut butter, mayonnaise, pickles, chocolate, milk, jelly beans and chewing gum (although Tom lied about the pickles and milk). Tom later admits to Mrs. Livingston that the success of making the sandwiches was due to one important factor: taking a good hit of bourbon before starting.
