However, these popular holiday themes seemed to have slipped from the awareness of my undisclosed colleague(s).
Please observe t

As Wikipedia defines:
"An Advent calendar is a special calendar which is used to count or celebrate the days of Advent in anticipation of Christmas.
I'm from a small town. I always thought I was slightly sheltered, not having more than 5 television channels and a duck as a pet. Nevertheless, I know what an advent calendar is, and how to operate one.Today, most Advent calendars are made for children. Many take the form of a large rectangular card with "windows" of which there are often 24; one for each day of December leading up to Christmas Day. One is opened every day during Advent. In many of these calendars, each window opens to reveal an image, a poem, or a portion of a story such as the Nativity story itself. More elaborate Advent calendars have a small gift concealed in each window, such as a toy or a chocolate item."
So, how in Rudolph's name did this happen?
I have but a few theories:
A) The Grinch does not know the purpose of an Advent calendar.
B) The Grinch knows the purpose, but is apathetic and simply doesn't care.
C) The Grinch believes this is a backwards Advent calendar, and is counting down from 25...
D) The Grinch is continuously extremely hungry and/or craving chocolate
E) The Grinch believes the Advent calendar makers saved the best chocolate for the end
Whatever the case, Merry Christmas you filthy animals!
