Sharona: Adrian, can I ask you something? And if it's none of my business, I promise I'll shut up.
Adrian Monk: I doubt it.
Sharona: What did Trudy mean by bread and butter?
Adrian Monk: Whenever Trudy and I were walking somewhere, we'd hold hands. If there was a lamppost or somebody walked between us, and we had to let go for a second, she'd always say "bread and butter." So when she died? Yeah, I think it was a message for me. She was saying, "I have to let go now for a little while but it won't be forever."
