As anyone who has tried to get out of Heathrow Airport alive knew from experience, that was not an easy task. Death and Gerald, having never been through Heathrow, mainly because Gerald was once a penguin and Death was once a semi-omnipotent being, had a bit of trouble finding the exit.
Many experts believed that Heathrow Airport may very well have contained some sort of nexus of the universe, a sort of Bermuda Triangle without all the sun and sandy beaches, and may possibly lead to another dimension entirely if one only located the right door. In 1993, an elderly, severely malnourished gentleman wearing grubby clothes and a serious amount of facial growth emerged from the south exit doors of Terminal 3 at Heathrow and screamed at the top of his lungs, "Frreeddoomm!"
