Lack of sleep
Rather than go to bed last night, I watched not one but two episodes of That 70's Show, both of which I'd seen before, followed by Forever Eden. And even though I think that show sucks, is boring, and the people are all idiots, I watched. The entire. Thing.

I will say in my defence, though, that I was not in my right mind yesterday. Being up for over 24 hours will do that to a person.
