Mrs. Rooster, picking up a lint roller: This seems pretty adept at picking up dust.
*rolls it across her table*
Mrs. Rooster: I should invent this. It's easier than a duster because you don't have to clean it off--you just strip off the tape.
Me: So how are you going to invent it? Patent the existing product for a different use and create a new product label for it? Oh, but then how will we get lint off your clothes now--buy a second one?
Mrs. Rooster: That's the beauty of my invention. It serves a dual purpose.
*rolls it across the top of her dusty-ass TV*
Mrs. Rooster: See?? It's so convenient! ...did you know that to dial Southwest Airlines in Spanish, you dial 1-800-VAMONOS?
Me: That's fantastic.
