On a side note, I own the Animated Series but I'm about to not own it, so I can own it again after Christmas.
You see, I found out this evening that my mom bought me the Animated Series for Christmas (a confirmation email from Amazon in my inbox. They sent it to me for some reason instead of her). She doesn't know I own TAS already, so I'm sneaking it into some old books I own and giving it to the Salvation Army thrift store, so that when I open my gift Christmas morning, she will have bought me something I don't own and she'll get to see me smile.
