SNL: Saturday Night Live

Saturday Night Live is still going strong after 43 years, and it continues to transcend generation after generation. NBC's Saturday Night Live has had its share of famous catchphrases over its run, however “That’s Hot!” is not one of them. Paris Hilton trademarked that famous catchphrase at the peak of her fame. She eventually ended up in a lawsuit against Hallmark, who used it on their greeting cards in 2007, although they claimed the cards were safe under the fair-use law.
