There must be at least a few of us who involuntarily think of an early '80s United States Postal Service PSA when dropping any mail into a mailbox. For decades, sending any mail has made me start hearing, "Good news travels better in a letter with the right zip!" That might explain why I check any zip code I write on an envelope at least twice. That habit started early, as that PSA aired frequently during the Saturday morning cartoons I watched when I was in grade school.
I watched that PSA on YouTube this morning for the first time in at least 35 years. I'd forgotten that Sammy Davis, Jr. and his father were in it, extolling the importance of using the right zip code. It's a testament to the jingle's staying power that I've never forgotten that chorus, however.
