Query: You must be joking!

Eighty-five bucks! For a jumped-up CD? How about I offer you four? Come on, haggle! You've got to haggle it's traditional innit? Still, I only want to buy the DVD, not the rights to the movie! Has the WORLD GONE MAD? FIFTY QUID to watch Mr. Creosote throw up again? To listen to that song about SPERM again? Some people may be completely bonkers about this stuff, but not for this much dosh? Oh no. What's so special about a 5" disk of plastique which makes it worth more than eight times a long thin piece of plastic tape (which I note can be had for under ten bucks). Huh? Think I'm stupid?::::::All right, you're on. Er, you can keep my name out of it can't you?
