Pennsylvanians: you've been waiting for this one. Here's my take on why we have "the case law," the uniquely stupid law that forces us to buy beer by the case -- nothing smaller! -- at off-premise retail.
Wouldn't it be nice to buy in any amount you wanted? Mixing sixes, picking sixes? Isn't it ridiculous that we can only dream about it, in 2009 AD?
Go. Read. Get incensed (and then write your legislator!).
