"I've vacuumed up enough crumbs to make a pie crust."
"What do you mean, it's not cheese? It's yellow, it smells weird...what is it, then?"
"Maybe acetone will get that out."
"I think it was juice. It's too sticky to be blood."
(after a full vacuuming) "A tooth on the floor? You didn't tell me anything about a tooth on the floor."
