Roger - "Liz, have you taken leave of your senses?"
"Next you'll be telling me you're turning Collinwood into a hotel! Why don't you do that, Liz - why don't you hang a sign out front and let out all the rooms!"
And of course, "My late sister's latest brainstorm."
But tongue twisting aside, you've got to love all of Roger and Liz' fights!!
