Exact lyrics will depend on when and where you learned the song:
Oh don’t you remember sweet Ratsy from Pike
Who crossed the wide kitchen with her alpha Ike
With two well-trained tabbies and one feeding bowl
The chocolate-chip cookies were their final goal.
Sing crunch-munch-munch, munch-crunch-crunch
Brux yum-yum chomp.
. . . Something like that, anyway.
