Three little maids from school are we Gilbert and Sullivan

[YUM-YUM, PEEP-BO & PITTI-SING]
Three little maids from school are we
Pert as a school-girl well can be
Filled to the brim with girlish glee
Three little maids from school!

[YUM-YUM]
Everything is a source of fun. (chuckle)

[PEEP-BO]
Nobody's safe, for we care for none! (chuckle)

[PITTI-SING]
Life is a joke that's just begun! (chuckle)

[YUM-YUM, PEEP-BO & PITTI-SING]
Three little maids from school!
Three little maids who, all unwary
Come from a ladies' seminary
Freed from its genius tutelary —
Three little maids from school
Three little maids from school!

[YUM-YUM]
One little maid is a bride, Yum-Yum —
