"Bad dogs, bad dogs chase the cat,
Chase the cat, chase the cat.
One dog's thin and the other dog's fat
On a summery Saturday morning.
They chase the boy on the rattly bike,
The rattly bike, the rattly bike.
Chasing things is what dogs like
On a summery Saturday morning."
Those bad dogs just can't help themselves chasing everything that moves, of course, and when a family of geese is roused out of the tall grass the "walk" goes haywire. Hilarity ensues, as we say.
