Quote from Hal in Burning Man
Lois: Hal, this place is so great! I met the nicest group of gals down by the Porta Potti's. They call themselves a "tribe," like a group of wild Indians. Isn't that cute? They invited me to the hemp-braiding tent later. Hal: What are you using the Porta-Pottys for when we have the world's greatest toilet ten feet away in the RV? That thing will suck down a small deer. [looks at the corwd] Mention free food and they start gathering like flies.
