When Sheldon protests, Leonard keeps sitting and eating, declaring “It’s my house and I’m tired of not sitting where I want.”
Later, when he, Penny, Sheldon and Amy are about to have dinner in the apartment, Leonard does the unthinkable…he sits in Sheldon’s spot on the couch.
As you can probably imagine, having a bit of success leads to Leonard taking one of the biggest steps ever for a character on The Big Bang Theory.
Sheldon leaves in a huff with his dinner and Amy, but Leonard couldn’t care less, noting to Penny that that moment was actually better than their post-work sex.
