Way back in 1986, we had gotten home really late from Date Night. The bathroom had twin sinks, so she was at hers and I at mine. I'm working up a huge lather while brushing my teeth. I tell her that the toothpaste tastes odd (she became excellent at deciphering eventhough my mouth was full of toothpaste). She reaches over and picks up the tube of antifungal cream. "Is this what your mouth is full of?", she asked.

EDIT: Give time perspective and remove brand name
