Through the front window of the office, I could see our big gay tridim sign plastered to a facing wall: WANTED—EXTRATERRESTRIALS! We had saturated MacTavish IV with our promotional poop for a month preceding arrival. Stuff like this: Want to visit Earth—see the Galaxy's most glittering and exclusive world?
