Quote from Lois in Hal's Christmas Gift
Lois: Okay, we'll make it work somehow. Just put it into four piles. [answers phone] Hello. Francis: [on the phone] Hey, Mom, good news. I decided to come home for Christmas after all. Lois: Francis, that is, um... great. What a nice surprise that you will be coming home for Christmas. Yes, We'll have the whole family here... exchanging gifts. Piama, too? Francis: Of course. We can't wait to see you! Lois: Well, we can't wait to see you. [hangs up] Hal: Six piles? Lois: Five. Piama and Jamie can share.
