What Would You Say Was The Darkest Moment of Season 1?

There were a lot of pretty dark scenes during season 1, such as the teenage con-artists getting their legs broken, or Jimmy's friend dying of a heart attack, but to be honest, I'd have to say the scene where Jimmy is announcing bingo would be the darkest moment of season 1. The way Bob Odenkirk acted for that part was really well done, in my opinion, when he stutters a bit and tries to go back to being cheery and happy, then he cuts off the game to tell his story about how he got a sexual offense charge, and finally when he drops the mic and walks out.

What do you guys think?
