My favourite episodes are "Beer" and "Potato". I love the whole concrete elephant speech. My favourite quotes in "Potato" are:
Walter: I bring you *something* beyond your wildest dreams Queenie: Are you sure sure? I've had some pretty wild dreams. I don't know what it meant but there was this one time where I dreamt there was a big tree and I was sitting right on top of it. And then one time I was a sausage roll.
Also when she reads out her poem, and when Walter enters and she talks to him in sailor talk, and puts the scope up to her eye with the eyepatch lol
