Today is not Martin Luther King, Jr.'s birthday. It is the day we observe his birthday. Is it so hard to figure out? He was born on January 15th, the same day as my father. It is my assumption that since my dad celebrates his birthday on the 15th that MLK, Jr's birthday is the same every year. I completely understand why his birthday is observed today, just don't look foolish next year and assume that because you have the day off (you must work for the government) it is MLK's actual birthday.
I will give everyone a pass on it this year since David Gregory screwed this up. For those that don't know him he is now the moderator of Meet the Press. Only people that are complete nerds watch that when they are in their mid 20s, I get that. While the rest of you watched the Eagles storm back I watched a rerun of the show and heard Gregory mention that King would be 80 today. I was stupefied by his idiocy, but managed to watch the rest of the show. I am sure I screw things up on a daily basis too so I will let it go. But just this once, David.
