I used to think that “greatest thing since sliced bread” was a stupid phrase. I mean how great is sliced bread really?
But then I started to think about it. Without sliced bread, you'd just get whole loaves handed to you. The only way to eat them would be to tear of random hunks of bread. Which would be fun for a while but it would get old, what with getting both the bread and your fingers dirty. Everyone would have to have their own loaves of bread.
And sandwiches would be completely out of the question.
Come to think of it, sliced bread is pretty great.
