Notes: With its fun subject matter and well known stars, one would think this deserved more than a support role for an Abbott and Costello caper at the Liberty. But no, there you go. Similarly it would up in the suburbs mostly below the bill, usually for Cheaper by the Dozen. Due to the weeks it secured and overall number of plays it did just creep into the top half of EF rankings for the year.
