Sheldon and Penny in “The Vegas Renormalization”

Sheldon

I can’t sleep on your couch. I sleep in a bed. And, given it’s dimensions I have no intention of living out E.M. Snickering’s beloved children’s book, The Tall Man From Cornwall.

Penny

Sheldon

There was a tall man from Cornwall whose length exceeded his bed. My body fits on it, but barely upon it, there’s no room for my big Cornish head.
