T-Rex: According to the Mayan calendar, the world will end in 2012!
T-Rex: The Mayans tried to warn us!!

T-Rex: Oh SHIIII-

Dromiceiomimus: According to the calendar in my computer, the world began on January 1st, 1970 at the very stroke of midnight!! It's impossible to make it go back earlier, and every moment is measured by the number of seconds since that one incredibly significant date! History is a lie! Unix software developers tried to warn us!!
T-Rex and Dromiceiomimus: Oh SHIIII-

Utahraptor: According to the calendar on my desk -
T-Rex: ...Yes?

Utahraptor: The world began on January 1st of this very year, and will end no more than 365 days later! The calendar is only 365 date-bearing pages dates thick and I've counted three times! The Page-A-Day publishing house tried to warn us!!
T-Rex and Utahraptor: Oh SHIIII-

Off panel: The Mayan Long Count calendar you're discussing doesn't end in our year 2012, it just rolls over to a new digit, much like the year 1 BC rolled over to 1 AD.
T-Rex: WHILE FACTUAL, THAT'S NOT A GREAT EXAMPLE BECAUSE THE GREGORIAN CALENDAR WASN'T ACTUALLY IN PLACE FOR THAT ROLLOVERRRRR-
