We can't say that we've ever looked at a SkyMall catalogue from our aisle seat and thought, "Gee, this would make a good song!" But we will be eternally grateful for this ditty by Nina Katchadourian, who flipped through the SkyMall and sang this: "Look at little doggie with his indoor restroom, but kitty's got a litter box that takes him to the moon!" And yes, it's a real thing. Litter Robot, SkyMall Collection APC101. All yours for $314.99.
