What is jam?

Famous quotes containing the word jam:

“We fight our way through the massed and leveled collective safe taste of the Top 40, just looking for a little something we can call our own. But when we find it and jam the radio to hear it again it isn’t just ours—it is a link to thousands of others who are sharing it with us. As a matter of a single song this might mean very little; as culture, as a way of life, you can’t beat it.”
—Greil Marcus (b. 1945)

“The rule is, jam tomorrow and jam yesterday—but never jam today.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

“If you hadn’t been in such a hurry to cremate me, I wouldn’t be in the jam I’m in now.”
—Seton I. Miller (1902–1974)
