No matter how successful you are, I want you to remember that you’ll presumably never be as famous as a cat that rose to fame via Internet meme. Grumpy Cat, in internet meme years, should have reached the point of “used only ironically” status. Instead, a pair of New York Times bestsellers, a Lifetime Original Christmas movie, and appearances everywhere from SXSW to Good Morning America ensure the continued relevancy of “Tardar Sauce” (Grumpy Cat’s birth name).
