What a deal! =D I'd get them if I didn't already have them.
Kidding aside, it's good that they're encouraging literacy and, er ... Pratchett-ness? Pratchetteria? (Like a cafeteria, but much better food, and for your brain?) Making up good words at 8:15 am (and with 15 minutes left before I have to go to work) is too difficult. I give up.
