Sophie and Mark in “Unfinished Business”

Sophie

...and I was quite shocked when you called Kathy a knucklehead, Mark.

Mark

No, I didn't.

Sophie

Yes, you did. You said she was a knucklehead and she should knuckle down or you'd knuckle her fat head. Then you stamped on Gerrard's foot.

Mark

That was an accident.

Sophie

No it wasn't.

Mark

But it could have been. I was careful to make sure that it could have been.
