I dunno about you, but it ain’t a holly jolly Christmas unless I can invoke Chico and Groucho Marx bantering over contract terms in A Night at the Opera:

Driftwood (Groucho): It’s alright, that’s in every contract! That’s what they call a “sanity clause.”

Fiorello (Chico): Ha ha ha ha ha ha ha ha… you can’t fool me. There ain’t no sanity clause!
