Lily: I bought groceries. That counts as changing something?
Barney: Lily, if I wanted a fridge full of groceries, or fresh coffee in the morning, I'd be in a relationship. But I don't want to be in a relationship. That's why I make it crystal-clear to every girl that walks through that door that this is not a place to leave a toothbrush. This is not a place to leave a contact lens case. This is a place to leave.
