Ravenously.
Taking a page from their own playbook, the members of Metallica consume both Cups in their own package in one bite (stacking the cups atop one another and swallowing them whole).
When this first orgiastic burst of gluttony has concluded, they look around for still more. Using semantic arguments which may or may not hold up in court, Metallica takes your Cups, your friends' Cups, and the Cups of anyone else within reach.
When pressed on their justification, they claim that all Cups are innately delicious and therefore their property. Further, they assert that anyone who has a problem with their hoarding of RPBC supplies can find another candy to enjoy; Metallica has no use for those who disagree with their sole ownership of the world Cup supply.
Cries of dismay at their rapacious attitude do little to dissuade Metallica from gobbling up any and all RPBC in the vicinity. Cup pundits validate or vilify Metallica's appetite for treats, doing nothing to clarify the issue or propose a satisfactory solution for anyone.
Perhaps most frustrating of all, those candy fanciers who lack the funding and legal support of Metallica are left holding empty wrappers and asking passers-by where all the Cups have gone.
>Whew. Sorry, I had to try a nodeshell rescue even though Ninja-Lad beat me to it.
Yes. Yes I did. Mwahahahahaha.
Pardon me. I had a little attack of megalomaniacal glee. I'm fine now.
