Sanctum

— Some mud man will be using our skulls for a soup bowl.
— That wasn't in the brochure, honey.

— See, it never occurs to him to ask if I actually like caving.
— Yep, Josh is his own man. He doesn't take after his dad much.

That hole looks pretty tight, Judes. Hope that diet is working for you.

In Xanadu did Kubla Khan
A stately pleasure-dome decree,
Where Alph, the sacred river ran
Through caverns measureless to man
Down to a sunless sea.
