In Which Everyone Helps Momlissa With Her Math.

[Momlissa is working on her grad-school homework at the dinner table.]

Momlissa [to herself]: What is an x with a line over it? What is s?

Cici: Well, x is probably pi.

Dadam: Yeah, she's probably right, it probably is pi. Just fill in pi and see what you get.

Momlissa [annoyed]: Okay.

Ruby: Yeah, x is probably pizza!
