extremes

a few days back, I heard someone make the following comment. he was describing different reactions to the advent of some new technology (I don't recall exactly what), saying that different people felt very differently. the two poles of reactions were described as follows: "it was the best thing since sliced bread, or the worst thing since the guillotine." wow. since it was during a formal research talk, I had to exert a massive effort not to laugh out loud. "the worst thing since the guillotine"? is that a common adage, or did the guy just make that up?
