One day some guy was hanging out with his friends, trying to tell them how great something was, and he said ‘It’s the best thing since sliced bread’. Everybody had a laugh, and the audience probably thought that guy was really clever. Then either that guy went around saying it all the time, or someone in his audience did,  otherwise we wouldn’t be saying it today. If it was the original bread slicing aficionado, he wasn’t that clever and just parroted the one clever thing he ever said. Whoever it was, a few people thought they were witty, but people who knew them well probably kept thinking ‘If I hear him talk about sliced bread one more time I’ll bunch him in the baby maker.”

Anyway, I don’t think sliced bread is that great.
