After capturing the hearts of the Internet, Grumpy Cat has been a busy cat, venturing to Disneyland, claiming The Iron Throne and in this Honey Nut Cheerios ad, meeting the cereal's mascot Buzz.
There are a lot of people who say that they're not morning people, but this ever-frowning feline isn't excited by any particular meal time. At one point in the video, Grumpy Cat even claims to be smiling, as indicated with some meme-like lettering on screen.
In the end, even a bright and cheery bowl of Honey Nut Cheerios isn't enough to get Grumpy Cat to crack a real smile, or show any interest in the breakfast cereal. Although the ad could have ended cheesily with Grumpy Cat forcing a smile, the ad admits in good humor that the cereal is "Part of a good breakfast for almost everyone."
