We take our funny card business very seriously because we recognize that many people connect with others through humor. Our partnership with Comedy Central is yet another example of our commitment to truly understand what consumers find funny so that we can be sure our products deliver on that," said Michael Brown, Vice President of Licensing for American Greetings. "Comedy Central is a destination for laughs for millions of people every day, and we're proud to be bringing the humor from some of the network's most recognizable shows to life in a new way."

In an effort to ensure the Company continues to create funny cards that resonate with consumers, the humor team at American Greetings conducted a six- month long research project to get to the root of what makes people laugh today. The findings revealed distinct differences in the way men and women use humor to communicate. As the result, American Greetings recently unveiled hundreds of new funny cards that appeal to a woman's sense of humor by highlighting the funny parts of everyday situations and experiences. The licensing agreement with Comedy Central, the #1 cable network in primetime among men 18-24 and men 18-34, allows the Company to create humorous cards that appeal to what men find funny, according to the research.

Hilton, 26, is suing for an injunction against the U.S. greeting card company and for damages in excess of $100,000, according to the suit filed late on Thursday in U.S. District Court in Los Angeles.

Kansas City-based Hallmark Cards said the card was part of a satirical series that parodied celebrities and politicians.

According to the lawsuit, Hilton's face is superimposed over a cartoon of a waitress serving food to a patron with the dialogue "Don't touch that, it's hot. What's hot? That's hot."

It says the card was selling in the United States for $2.49.

The suit says that Hallmark failed to obtain approval from the hotel heiress for using her image and had damaged her rights to privacy and publicity.
