Cover Art

The single's cover art is a direct take-off of the National Geographic magazine's distinct front cover. In fact, the top part of the cover says in a tongue-in-cheek manner, "Color Pullout Centerfold: The Inner Cavities of Sum Yun Guy (Page 182)" while the bottom reads "The Journal of the National Geographic Society, San Diego, CA."
