"Two by two"
"In an old house in Paris that was covered with vines
Lived twelve little girls in two straight lines
In two straight lines they broke their bread
And brushed their teeth and went to bed.
They left the house at half past nine
In two straight lines in rain or shine-
The smallest one was Madeline"
-Ludwig Bemelmans, Madeline, 1939
