I worked in Hoarders Books, and we always knew when Oprah was on: 4 pm.
Like clockwork, people would start to trickle in by 4:15 (seriously, the show wasn't even over yet) asking for her newest endorsed book. And like clockwork, we would run out after two or three people bought it.
Then we'd get people for the rest of the week who would be upset about having to special order it and having to wait for it to arrive.
Well excuse us for not knowing what the hell she was going to endorse! If she had bothered to give bookstores a two week head's up, we could have stocked up on the damn things for you.
Since she didn't, you --poor, poor baby that you are-- will just have to wait for the damn thing to get here and suffer the abject dragged-behind-a-car-though-the-mud-agony of not reading it right away!
