Maybe the grandmother was a member of "The Anaheim, Azusa And Cucamonga Sewing Circle, Book Review And Timing Association," a group of drag racing grannies in the song by Jan & Dean which probably had the longest title of any rock song. Actually, the title is better than the song. I love the way the title starts off so innocent and mundane and then you get to the words, "Timing Association" and it's like "Uh-Oh."
