Two little white girls, flying in the mathematics department, flying, flying, muah, muah;
Two little house girls, flying on Arbor Street, flying, flying, ah ah (pia pia);
Two math girls, flying in the small countryside, flying, flying, pia pia...
Hey, why don't you say it?
Oh, I forgot.

The hilarious life of two math girls has nothing to do with love, just friendship.
There are countless bits and pieces in life.
