“But, Bowser, don’t you recall that our Doctor Butterfield worked out in the laboratory that the Human Eye Can Only Rivet on Seven Words at Once? Your slogan has nine. If you could somehow boil it down——”

“I’ll boil nothing down. I like it as it is.”

Mr. Bowser shrugged his well-tailored shoulders.

“And fly in the face of psychology?” he asked gently, but as one who is hurt.

Mrs. Bowser bridled.

“Don’t look at me as if I were a naughty child, Bowser!” she ejaculated. “I’m not a green copy writer that you’ve caught wearing an unadvertised brand of rubber heels. I was a Successful Slogan Builder before I ever met you, please remember.”

“Come now, control yourself. At least let me tell you about the Big Thought I just had before I came in here.”

Mrs. Bowser tapped her teeth with her pencil. Mr. Bowser jumped to his feet and when he spoke his voice held chords of rapture and his eyes were alight with the joy of creation.

“Listen,” he began. Then in his special slogan voice he declaimed: “Smelly-Welly—dirt-devourer!”

Mrs. Bowser regarded him without enthusiasm.
