Frank and Liam in “Unfinished Business”

Frank

She's a hot piece of ass, your mother! Don't get me wrong. But within that fine mortal husk lies a rotting pile of filth, and I don't want her soiling you, so, from now on, you fight.

Liam

Fight Mama?

Frank

Yes, my son. Fight her with every muscle in your wee body, or she will drag you into her pit of despair and murder your soul. So... Remember, whenever you see the blonde woman with the green boots and the blue parka, you yell, "Stranger, danger," and kick her until an adult shows up.
