Q: In a few weeks something will happen that hasn't happened since 1987. What is it?Wait? Will "The Simpsons" be going off the air? Now that would be different.
Edit: The main hint was the word "different". The other hint was the image from the Simpson's episode "Future Drama" set in the year 2013.
A: 2013 will be the first year since 1987 to have no digits repeated (1988, 1989, ..., 2011, 2012). At least we didn't have it as bad as they did in the 12th century going from 1098 to 1203 with all the intervening years of repeated digits (1099, 1100, 1101, ..., 1199, 1200, 1201, 1202). Oh how agonizing that must have been for them!
