Today is a momentous, miserable occasion. This is the first birthday of everybody’s favorite misanthropic kitten, Grumpy Cat — and everybody’s celebrating. There are even Grumpster Cat birthday postage stamps! It’s hard to believe that just one year ago, the world was Grumpy-free. How did we express our dry wit and humor without her? The world has truly become a better, more grumpy place thanks to Tarder Sauce. So even though we know she probably hates birthdays, and parties, and anything fun at all, we’re happily wishing Grumpy Cat a most unhappy birthday.
