What's Your Favourite Episode From Season Three?

Yes, I've asked about Seasons One and Two. Now I want to know about Season Three. I have just finished watching Season Three and my favourite Episode has to be "Bad Day At Black Rock".

Why is this one my favourite? Because we get a giggle at Sam and his bad luck. I could not stop laughing at all his bad luck. I know I shouldn't laugh, but I was totally GIGGLED up. Especially at the part when he loses his shoe. He gives Dean such a pathetic look you feel sorry for him but can't help laughing.
