One, Two, Buckle My Shoe

One, two,
Buckle my shoe;
Three, four,
Knock at the door;

Five, six,
Pick up sticks;
Seven, eight,
Lay them straight:

Nine, ten,
A big fat hen;
Eleven, twelve,
Dig and delve;  [alt: "Who will delve?"]

Thirteen, fourteen,
Maids a-courting;
Fifteen, sixteen,
Maids in the kitchen;  [alt: "Maids a-kissing;"]

Seventeen, eighteen,
Maids a-waiting
Nineteen, twenty,
That's a-plenty. 

[Alternate last line: "My plate's empty."]
