I have been buying the Simpsons wall calenders for a few years now, and I love them. They are fun, silly, and remind me of shows past. Along with all of them is also a full two-page poster in the middle.
I also like that they generally have a lot of holidays and birthdays listed for people that you normally don't here about, old famous writers and actors, it is a joy to look at every day, not to mention a good collector's item as well.
I will not go another year without getting one of these anymore.
