Mad Men
I ran through all seven seasons of Mad Men in one week back when I was in college (which was more than a hot second ago at this point in my sad, late twenties life). Needless to say, I loved it. Interestingly enough though, I don't remember anything.
It's pretty amazing to find such a total blank spot in your memory. At one point I know I learned calculus. But it's not like I've been confronted by an integral equation mocking me and my poor memory.
I do remember the very last scene in the series finale, but I would never be able to work out how it got there. And even if I could, I'd still be watching this show again just for the outfits.
