Persistent earworm alert CXI

Strangely, Toni Basil's "Shopping From A To Z" has infiltrated my mind today.  I've never listened to the entire song, but I know Basil deserves credit for admitting that she didn't buy anything starting with the letter X.  Even today, when you can buy yogurt and a lawn chair from the same store, it would be stretching things to say that you bought an x-ray machine or a xylophone from the same store that sells apples and liver.
