> My rule of thumb is that if I went into a restaurant and asked the waiter "I want a sandwich, but I don't care what kind -- surprise me!" and they brought me an object, how angry would I be at the waiter who brought me that object. Despite the fact that you're clearly a mental patient who thinks that a bagel with some meat inside can be a sandwich, you have my upvote for that line:-) Seriously, though, that's actually a pretty good criterion. Reminds me of Justice Potter Stewart's comment about knowing it when he sees it: if I ask for X, someone gives me Y & I'm angry, then Y is not in the class of X to a degree directly correlated with my anger at the result. I dig it!
