Maura explains her heritage

Maura and Erin are home coloring right now (I'm so jealous), discussing the crayons, and the following conversation takes place:

Erin: I like purple or green. They are my favorite colors.

Maura: You like green because you're Irish. I'm Irish, too. That's why I like green.

Erin: You're right. You are Irish. Do you know what else you are?

Maura: I'm Irish. That's why I like green. And Italian. That's why I like pasta. And, I'm a polar bear.
