Cases in point...
The other night, Laurie mentioned that she had picked up a new can of coffee and it was Chock Full o Nuts. With that, both of us started singing, "Chock Full o Nuts is that heavenly coffee, heavenly coffee, heavenly coffee. Chock Full o Nuts is that heavenly coffee. Better coffee a millionaire's money can't buy." (You can sing along at http://www.chockfullonuts.com/questions.aspx# ) I don't know just how far back that jingle actually goes, but I'm sure I first heard it in a TV commercial more than half a century ago.
And remember it all these years later.
Chuck and Rebecca visited recently and Laurie mentioned that a candy bar she had was similar to a Chunky. For those who, like my son and daughter-in-law, are unfamiliar with it, a Chunky is a small block of chocolate with raisins and peanuts in it. Unlike other chocolate candies -- like Hershey's and Nestle's bars -- which were flat, a Chunky was like a chocolate ingot. Their slogan was "Open wide for Chunky," something else that Laurie and I both recalled these many years since we've actually had a Chunky.
In a similar vein, we were at the railroad station last week and when the train pulled in, Laurie made a comment about shaking a box of Good & Plenty. Choo-Choo Charlie was the cartoon character "spokesman" for Good & Plenty and his song is another jingle I can still recall... and sing. (You can check out the original commercial on Youtube: http://www.youtube.com/watch?v=ExSlyoVTX3I )
Finally, there's the Chevrolet song that was revived in a commercial starring the cast of Glee last year. This is one for which I don't know many of the words beyond, "See the U-S-A in your Chevrolet... lala lala lala lala lalaaa...!" But, hey, I remember the most important part and, as far as the Mad Men were concerned, that's what counts!
