Hallmark has a new line of cards called Pop Goes the Culture. The cards feature famous lines from popular television shows like Lost and Grey's Anatomy. Other cards in the new line feature quotes from celebrities including Bill Maher, J.K. Rowling and Gwen Stefani. An article on MLive.com about the Hallmark cards gives the following examples.
"Once in a blue moon, people will surprise you ... and once in a while, people may even take your breath away,'' reads one quote from "Grey's Anatomy'' on the outside of a card, with this on the inside: "Thank you for making mine a lifetime of blue moons.''
And there is this from Lost: "You're one of the good ones" on the outside of the card, and inside, "... and I'm one of the lucky ones. Very lucky."
Rocker Gwen Stefani and author J.K. Rowling, the movie Top Gun and TV shows The Office and Cheers are among other sources.
