Once upon a midnight cautious while I pondered weak and nauseous
Over some advertising copy I had done for Woolworth's Store,
While I nodded nearly napping suddenly there came a yapping
As of someone loudling yapping, yapping at my office door.
"'Tis some client there," I muttered, "yapping at my office door.
Only this and nothing more."

Then I felt my terror worsen for my guest was not a person
In there stepped a cocker spaniel; naturally I jumped in fear,
Tried to climb an oaken panel, ripping there my new grey flannel,
But the Spaniel merely stood there speaking out with voice so clear,
Speaking out like Jack Lescoulie in voice both loud and clear:
Quoth the spaniel, "Drink Blatz Beer."

I marvelled that this dog ungainly spoke commercials very plainly,
How he spoke the message clearly, selling points he underscored,
For I could not help agreeing that no living human being
Ever yet could mouth a slogan without sounding slightly bored.
Most announcers being human can't help sounding slightly bored.
Quoth the spaniel, "Buy a Ford."

Thus this dog with voice like Murrow, made my heavy brow unfurrow.
Thoughts of fortunes I could make now made me shake down to my knees.
But the spaniel set my grieving then by turning tail and leaving.
Naturally I begged him tarry crying out, "Stay with me, please!"
Chasing him right down the hallway crying out "Stay with me, please!"
Quoth the spaniel, "Eat Kraft Cheese."
