I don't know what I was expecting when I turned on CBS and saw Lindsay Lohan sitting there talking to David Letterman, but what I got was sort of painful to watch. Although like any good train derailment, I could not turn away. Apparently, the Letterman staff never told Lindsay that talk about her next stint in rehab was fair game. She thought she was going to waltz in, answer lobbed questions about Scary Movie 5 and leave. Nope. She wasn't exiting that stage before she got lectured by Dave about getting her shit together and tears came out of her eyes. Now, I'm usually a first responder when it's time to shit on someone, but for her part, Lohan handled it all pretty well.
