I am wondering how many who have seen the commercial for the U.S.P.S Priority Mail Flat Rate shipping box, featuring a tie in to the new Pixar Toy Story 3, know why Hamm the piggy bank was put in the mailman's cap.  It was the inspiration for today's Mail Music Monday.   If you know the answer please let us know by posting a comment to this blog or on our Facebook page.
