The very evil Riverwind (you can tell by his facial whiskers) saw an opportunity to take over the EA. Later that night, he sneaked into the kitchen and removed the word "anything but" from all three slips.
And so it was that, at noon next day, overlooking a cliff, the three sat down and opened their lunch boxes. When Bboy saw the penis sandwhich, he leaped to his death rather then eat it. Paolol jumped when he saw the plate of Rocky Mountain Oysters, and Andrew jumped when faced with another dish of haggis.
Of course, the police had no trouble finding the requeat cards and noting how the words "anything but" had been scratched out, and matched the ink on the paper to a pen Riverwind always carried.
And so it was that the Police put Riverwind in handcuffs, and charged him with the murder of Bboy and Paolo. "But what about Andrew?" asked Riverwind, looking at Talula.
"Don't look at me like that. At the last minute, Andrew decided to pack his own damned lunch."
