I think "I Know About the Holograms" needs to be added to the Balloon Juice Lexicon. I've written up a definition, if I'm ever lucky enough to get it in:
"I Know About the Holograms" - A derisive phrase used to mock people bizarrely out of touch with what 99.99% of us would call "the real world," including the man who actually said it, Sen. Ben Nelson (D-Neb). In a discussion about ATM fees, Nelson had just disclosed that he wasn't familiar with them—because he had never used an ATM before. As a way of defending himself for being so out of touch, Nelson said, "I know about the holograms." He meant "bar codes," which made his being out of touch even farther—and more hilariously—out of touch.
