Grumpy Cat is apparently on a mission to meet the grumpiest, most beloved characters and dethrone each and every one of them. Last week she made Grumpy, of the seven dwarfs, look downright chipper.
Today she goes head to head with Oscar the Grouch.
"I know what you're doing: You're searching for videos of disgusting cute little kitties," Sesame Street's resident grouch barks at the beginning of the clip. "I have something better. If you want kitties, check out my new best feline friend: Grumpy Cat."
The two, who met at Mashable's headquarters, then enter a grouch-off to determine which is more "crabby, cranky and cantankerous." You'll have to watch the video to see who wins, the Grump or the Grouch.
We will say this much: Grumpy Cat (born Tardar Sauce) is looking particularly grumpy today.
And joke's on you Oscar, because this was as adorable as any kitty video on YouTube.
