Brand Loyalty

The toothpaste that I use is Crest.
I cannot tell if Crest is best;
But it’s the brand I’ve always used.
A change would get my teeth confused.

For laundry, what I buy is All;
A prior brand I can’t recall.
My clothes get clean; I like the smell.
A switch would not serve quite as well.

My ketchup’s Heinz, my dressing’s Ken’s.
Purdue’s the brand I like for hens.
My soap is Yardley; Listerine
Is what insures my breath is clean.

What advertisers understand
Is how much power they command;
But customers they love to see
Are loyal sticklers, just like me!
