It's just a couplet; of course there will be other words, but they won't matter. Listen:
Cousin Teresa takes out Cæsar,
Fido, Jock, and the big borzoi.
A lifting, catchy sort of refrain, you see, and big-drum business on the two syllables of bor-zoi. It's immense. And I've thought out all the business of it; the singer will sing the first verse alone, then during the second verse Cousin Teresa will walk through, followed by four wooden dogs on wheels; Cæsar will be an Irish terrier, Fido a black poodle, Jock a fox-terrier, and the borzoi, of course, will be a borzoi. During the third verse Cousin Teresa will come on alone, and the dogs will be drawn across by themselves from the opposite wing; then Cousin Teresa will catch on to the singer and go off-stage in one direction, while the dogs' procession goes off in the other, crossing en route, which is always very effective. There'll be a lot of applause there, and for the fourth verse Cousin Teresa will come on in sables and the dogs will all have coats on. Then I've got a great idea for the fifth verse; each of the dogs will be led on by a Nut, and Cousin Teresa will come on from the opposite side, crossing en route, always effective, and then she turns round and leads the whole lot of them off on a string, and all the time every one singing like mad:
