It's late Saturday morning as we look in on the Andrews family in Riverdale and we find Mr. Andrews in the living-room seated at his desk just completing a job that millions of American fathers had to do this week. He's filling in his income tax form! He gets Archie go and put it in the mailbox on the corner of the street and then remembers he has forgot to put the $500 they have given to charity on the form, which would have saved him $50 in tax. Now how can they get the letter back from the mailbox!
